Prefix-list; clear bgp peer-group Test soft in; no file prompt quiet
Hello everyone,
I have a few simple questions. Hope someone will help me Thank you in advance.
1) We are using prefix-set into route-maps, but how I can use a prefix-list?
2) In classic IOS we have the command: clear bgp peer-group Test soft in
I don't see it in IOS-XR (Cisco IOS XR Software, Version 4.0.1):
RP/0/RSP0/CPU0:STH02#clear bgp ipv4 unicast ?
* Clear all peers and all routes from the BGP table
A.B.C.D or X:X::X BGP neighbor address to clear
as Clear peers in a specific AS
dampening Clear route flap dampening information
external Clear all external peers
flap-statistics Clear flap statistics
nexthop Clear nexthop
self-originated Clear redistributed, network and aggregate routes originated here
shutdown Clear all peers which were shut down due to low memory
3) In classic IOS we have the command: no file prompt quiet
I don't see it in IOS-XR. What is the command for IOS-XR?
I need it for the operation like this:
copy ftp://**:***@216.*.*.*/CUST_AS-TEST-in.prefixlist compactflash:/PrefixFilters/CUST_AS-TEST-in.prefixlist
Wed Apr 18 12:02:00.936 UTC

Thank you Alexander for your reply. It is the good RPL description and I've got the idea of REFRESH capable peer.
BUT, I still don't find the answer on my 3-d question:

New to EEM, i wanna soft reset BGP when a prefix list is applied
Hello,
This is my script:
event manager applet SOFTRESETBGP_IN
event cli pattern "neighbor 10.0.0.2 prefix-list.* in" sync no skip no period 1
action 1.0 cli command "do clear ip bgp 10.0.0.2 soft in"
action 2.0 syslog msg "BGP PEERS SOFT RESETED IN"
event manager applet SOFTRESETBGP_OUT
event cli pattern "neighbor 10.0.0.2 prefix-list.* out" sync no skip no period 1
action 1.0 cli command "do clear ip bgp 10.0.0.2 soft out"
action 2.0 syslog msg "BGP PEERS SOFT RESETED OUT"
When I issue the "neighbor 10.0.0.2 prefix-list A in" command it displays the pre-defined syslog msg, but the peer is not reseted.
Test:
R1(config-router)#do sh ip bgp

When I do manually clear the peer, the policy applies:

I have also tried to clear both direction without ".*"
event manager applet SOFTRESETBGP
event cli pattern "neighbor 10.0.0.2 prefix-list" sync no skip no period 1
action 1.0 cli command "do clear ip bgp 10.0.0.2 soft"
action 2.0 syslog msg "BGP PEERS SOFT RESETED"
result is the same...skip no means: execute the command (you can skip it)
sync no means: you have to execute the CLI command, then the EEM script runs
example to skip:
R1#sh running | b event
event manager applet OSPF
event cli pattern "clear ip ospf process" sync no skip yes period 1
end
R1#clear ip ospf process
R1#
without "skip"
R1#sh running | b event
R1#clear ip ospf process
Reset ALL OSPF processes? [no]: y

Hello All,
I'm working in a BGP prefix list configuration and i'm seeing a strange issue.
Issue: As per the cofiguration we have defined the prefix list to filter the incomming subnets. Though a specific subnet is not allowed in the prefix list but the router is allowing the subnet to get in to BGP table from the neighbour.
configuration:
ip prefix-list TEST seq 5 permit 10.61.64.0/19 ge 24 le 24
Though the below subnet is not allowed in prefix list but I'm seeing this subnet in BGP table with best path.
10.61.192.0/23
Can you anybody help me to know what could be the issue? any bug? any thing I'm wrong with the configuration?
Thanks,
ThiyaguHi,

Strange Problem in dynamically list population with record group
Hello Room,
I am dynamically populating a single list with 2 record groups. I am having a strange problem. All the code are written in 2 seperate buttons. The code of every button is given below.
Button 1 code:-
DECLARE
rg_reports RECORDGROUP;
rg_name VARCHAR2(40) := 'REPORTS';
vTemp NUMBER;
BEGIN
-- Pls make sure Group doesn't already exist
rg_reports := FIND_GROUP(rg_name);
-- If it doesn't exist then create it and add ur query to it
IF Id_Null (rg_reports) THEN
rg_reports:=CREATE_GROUP_FROM_QUERY(rg_name , 'SELECT companyname,to_char(co) from companymaster order by companyname');
end if;
--Populate the Record Group
vTemp:=POPULATE_GROUP(rg_reports);
POPULATE_LIST('REPORTS.EXAMPLELIST', rg_name);
Delete_Group( rg_reports );
END;
Button 2 Code:-
DECLARE
rg_reports RECORDGROUP;
rg_name VARCHAR2(40) := 'REPORTS';
vTemp NUMBER;
BEGIN
-- Pls make sure Group doesn't already exist
rg_reports := FIND_GROUP(rg_name);
-- If it doesn't exist then create it and add ur query to it
IF Id_Null (rg_reports) THEN
rg_reports:=CREATE_GROUP_FROM_QUERY(rg_name , 'SELECT accountname,to_char(co) from accountmaster order by accountname');
end if;
--Populate the Record Group
vTemp:=POPULATE_GROUP(rg_reports);
POPULATE_LIST('REPORTS.EXAMPLELIST', rg_name);
Delete_Group( rg_reports );
END;
The code is same here only the sql is different in these 2 buttons. Now the problem point.
when i press button 1, I get the list populated ok. when i try to click on the list item and keep the button pressed the list gets scrolled properly.
when i press button 2 after that i get account names well populated in the same list item as well, but this time, when i keep the button pressed the list does not scroll below as in button 1. It does not even allow to select different item from the list of button 2 code.
I tried to clear cache, cookies, exit browser everything and try to run the button 2 first, but still the problem in button 2 code.
Following are my system details.
windows 7 professional edition.
Oracle database 11g on windows 7
Oracle forms 10g patchset 10.1.2.0.2 on windows 7
Browser Netscape Navigator with oracle jinitiator 1.3.1.22
But this form is run by a client side html file where oracle forms 10g is not installed on windows xp. html file is just referring server url to run the module. The file is run on Netscape navigator browser with oracle jinitiator 1.3.1.22
My question is that is this a bug ? if button 1 gets the list item scrolled, why is the problem with button 2 even though i press it first. Here I am deleting the record group also. after the code is over. Initially I thought this may be the character length problem so I took the maximum character length for that list item as given by the 2 columns in database.
Why is the list scrolling not happening in button 2 but in button 1 with same codes on both ?
Anybody please help me.The problem is the second query. I would guess that the TO_CHAR(co) is not unique for each account, but is the same for the accounts. And as the second item in the select-list is the listitems values, all your listitem-entries have the same value. therefore, of you select any entry, the list will always go the the first entry again.
Adjust your query. -
List.clear() outside of List finalList = new ArrayList(); will delete element in finalList?
Hello all!
I am using 3 ArrayLists.
the first is List<String>
the second is List<String[]>
and the third is a list of those lists List<List>
I use the first list to get the string I need, but I use the second for String.split.
I then need to keep a list of these to use, so I need the third List.
After adding the second list to the list of lists I want to clear it so I can set up the next list to be added, but if I do list.clear(); it will delete everything in that list.
If I do not clear it, it is fine.
At first I wasn't sure if it was my fault, because I'm not sure if I ever had to do that before, so I made a test case that yields the result if I change the element outside.
* To change this template, choose Tools | Templates

package javaapplication1;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

public class JavaApplication1 {

String a;
List<String> j = new ArrayList<>();
public JavaApplication1()
a();
public void a()
a = "ADASDSADSA";
j.add(a);
a = null;
System.out.println(j);
public static void main(String[] args) throws SQLException {
JavaApplication1 a = new JavaApplication1();
If I change a = null to a = ""; it still yields the original a = "ADASD......";
protected List<String> list = new ArrayList<>();
protected List<String[]> list2 = new ArrayList<>();
protected List<List> finalList = new ArrayList<>();
finalList.add(list2);
//list2.clear();
With this I yield an empty array element, even though my array elements exist. I tried using multiple lists and I just had multiple empty elements.
So again I'm not sure if I did something wrong, or is this a bug? Since my test case worked, I'm confused.
Thanks!
~KZAfter adding the second list to the list of lists I want to clear it so I can set up the next list to be added, but if I do list.clear(); it will delete everything in that list.
Correct - you are just working with multiple references to the SAME set of objects.
Use 'remove' to remove an element from a list and then 'add' to add it to the other list.
See the Javadocs for the 'remove' method of the List interface
http://docs.oracle.com/javase/6/docs/api/java/util/List.html#remove(int)
remove
E remove(int index)
Removes the element at the specified position in this list (optional operation). Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.
Parameters:
index - the index of the element to be removed
Returns:
the element previously at the specified position
Throws:
UnsupportedOperationException - if the remove operation is not supported by this list
IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size()) -
PIX 501 - prefix-list causes PDM to fail
Hi
I am configuring a redundant link via ADSL between 2 501 routers
I cant get the link to activate when the system is connected to the local network because it picks up a OSPF route to the remote site via the main internal network.
I tried to ad a filter to prevent the the route being recieved. And here is my problem
Either using PDM or the command line, the creation of a filter
prefix-list mel-backup seq 9 deny melbackup/30 causes the PDM to lock on startup or save.
And the area filter command seems to have no effect
I even tried a random internal route.
The commands I am adding are
prefix-list backup_melb seq 3 deny Level9/24
router ospf 22
network 10.150.102.22 255.255.255.255 area 0
area 0 filter-list prefix backup_melb in
Does anyone know of a problem with this ?
Thanks in Advance
Mark CaseyHi,
PIX501 is a very very old Cisco firewall that has not been sold for a long time to my understanding. It also doesnt support even close to new software levels.
If you wanted to replace the PIX501 the corresponding model nowadays would be ASA5505 which is the smallest Cisco ASA firewall with 8 switch port module. There is already a new ASA5500-X Series (while ASA5505 is of the original ASA 5500 Series) but they have not yet introduced a replacing model for this model nor have they stopped selling this unit. I have a couple of them at home. Though naturally they are more expensive than your usual consumer firewalls.
But if you wanted to replace your PIX firewall then I would probably suggest ASA5505. Naturally you could get some other models too but the cost naturally rises even more. I am not sure at what price these are sold as used.
I used some PIX501 firewalls at the start of my career but have not used them in ages since ASA5505 is pretty much the firewall model we use when we need a firewall/vpn device for a smaller network/branch site.
Here is a PDF of the original ASA5500 Series.

http://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/at_a_glance_c45-701635.pdf
I am afraid that its very hard for me atleast to troubleshoot this especially since I have not seen any outputs yet. Also the very old CLI and lack of GUI (?) make it harder to see what the problem is.
Could you provide the requested outputs?

Hi Yogesh,
Prefix lists are more sophisticated forms that Cisco provides for filtering BGP route advertisements. They filter on IP address just as distribute-lists do, however they are easier to read, and require fewer commands to configure.For example
prefix-list xx seq 10 permit 43.10.0.0/16 ge 18
The statement above allows any route announcement in the range of 43.1.0.0 - 43.1.255.255 but that announcement must have a length greater than 18 bits in the mask. This permits you to allow announcements in the range, but not an announcement equalling the entire range (/16), or even announcements of half the range (/17). Only announcments with a length "greater than or equal to" /18 will be permitted.
With your configuration only /24 and /23 in the network will be out via prefic list for vsnl and vice versa for bharathi.
Check out the below link for more information and implementation of prefix list
http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a008009456d.shtml
Hope to Help !!

Ip prefix-list modification help
i need to modify my internet edge bgp advertisements to exclude a small slice of the end of our ip space and i can't wrap my brain around what i need to do to modify the prefix list. my company uses the 192.168.0.0 thru 192.168.11.255 ip space and shown below in our existing bgp configuration (slightly modified to protect the innocent). I want to cut out the very last /29 net out of the 192.168.11.0 network.

Any help that anyone can provide is much appreciated!i tried applying your suggestion and we still saw the larger 192.168.8.0/22 supernet being advertised... still missing something.
i tried writing the prefix-list explictitly stating only the networks i wanted advertised but something went wrong and we lost some internet connectivity from the outside so i had to pull things back to the way they were. this is what i tried:
first i added lines 75 thur 105 so the list looked like this:
ip prefix-list stateofnh-list seq 65 deny 192.168.11.248/29 <- your suggestion applied
ip prefix-list stateofnh-list seq 70 permit 192.168.0.0/21 le 24 <- original line
ip prefix-list stateofnh-list seq 71 permit 192.168.8.0/22 le 24 <- oiriginal line
ip prefix-list stateofnh-list seq 75 permit 192.168.8.0/23 <- new stuff starts here
ip prefix-list stateofnh-list seq 80 permit 192.168.10.0/24
ip prefix-list stateofnh-list seq 85 permit 192.168.11.0/25

ip prefix-list stateofnh-list seq 105 permit 192.168.11.240/29
then i removed lines 65 and 71 leaving just this:
ip prefix-list stateofnh-list seq 70 permit 192.168.0.0/21 le 24 <- original line
ip prefix-list stateofnh-list seq 75 permit 192.168.8.0/23 <- new stuff

ip prefix-list stateofnh-list seq 105 permit 192.168.11.240/29
but like i said, suddenly several sites we host became unavailable from and i quickly peeled everything back. suggestions? -
Change an extend access list in a prefix list
Hallo All,
I would like to translate an extend access list in a prefix list.
ip access-list extended x_to_y
permit ip 1.1.1.1 0.0.1.255 any
deny ip any host 3.3.3.3
Any hint?
Thanks!!!Hi Fabio,
I am sorry but to my best knowledge, this is not going to work.
You want to perform Policy Based Routing (PBR). For PBR, the packet selection is based on inspecting their header values by an ACL. A prefix-list does not inspect header values; rather, it would inspect routing update contents. This is also the reason why you cannot figure out how to rewrite the second line - because a prefix-list does not have a source-and-destination semantics. It is simply a list of network addresses you would be looking for in routing protocol updates.
Even the documentation at
http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_pi/configuration/15-mt/iri-15-mt-book/iri-pbr.html
clearly shows that the only supported match commands are match length and match ip address - not match ip address prefix-list.
I wonder - how come that your platform is unable to accomodate an ACL for PBR in hardware? Can we perhaps try to make this work? A prefix-list is not the way to go.

BGP Peer down monitoring through SNMP Traps
Hello,
I'm trying to figure out how I can monitor with BGP peer went down using SNMP traps or any other methods that are out there. Basically I would like to get a trap that tells me the IP address of the peer that went down.
Looking over the SNMP MIBs for BGP all i can find is snmp traps that tell me there was a change in states in BGP, but don't say which neighbor.
Is there any way to get such information? Would I have to use EEM with some script? This seems like a very common thing that people would want to know.
Thank you in advance,
TomSNMP notifications can be configured on the router and GET operations can be performed from an external management station only after BGP SNMP support is enabled.
SUMMARY STEPS
1. enable
2. configure terminal
3. snmp-server enable traps bgp [state-changes {[all] [backward-trans] [limited]}] | [threshold prefix]
4. exit -
MIB and BGP peer (BGP4-MIB::bgpPeerRemoteAddr)
Hello,
We're using NAGIOS to monitor the networks of our customers.
We're using BGPv4 and vrf lite on many of those networks.
On every remote routers, we have multiple bgp peer sessions facing two ASR-1002F backbone routers (GRT and VRFs...).
I'd like to know if there's a way to monitor all bgp sessions, on a remote router, without having to enter the ip addresses of all neighbors....
I'm wondering whether or not I can use the "bgpPeerState" state to monitor the status of these bgp peer sessions?
Someone got an idea?
Thanks in advance,
BRGs

Thanks for your answer.
We've been testing some scripts and it's now working!
We use the bgpPeerRemoteAddrMIB to get our ip @ and then we log any change in bgpPeerStateper ip@...
An alarm is on when we have an IDLE state....
Warning for the other BGP states
OK for established.

Difference between list.clear() and new instance
In the below code,
List<String> test = new ArrayList<String)();
list.add("one");
list.add("two");
list.add("three");
list.clear();
(or)
list = new ArrayList<String)();
list.add("four");
list.add("five");
What is the difference between List.clear() and creating new instance for list?1. Use code tags to post codes -- [code]CODE[/code] will display asCODEOr click the CODE button and paste your code between the {code} tags that appear.
2. Invoking clear() sets all the elements of the ArrayList to null and resets the size to 0. public void clear() {
modCount++;
// Let gc do its work
for (int i = 0; i < size; i++)
elementData[i] = null;
size = 0;
}(modCount is used to detect concurrent modification and throw an Exception when needed)
Constructing a new ArrayList creates a new, different, empty ArrayList.
In many situations they might be equivalent, but not in a case where you have two or more variable references to the same ArrayList. Example (watch out for typos)ArrayList<String> stringsA = new ArrayList<String>();
ArrayList<String> stringsB = stringsA;
: // add elements to stringsA
: // stringsB refers to the same populated list
stringsA.clear(); // stringsB refers to the clear()ed list
: // add elements to stringsA again
stringsA = new ArrayList<String>(); // stringsB still refers to the populated listdb -
A little bit confused about the ipv6 prefix-list
when I configured ;
ipv6 prefix-list abc permit ::/0 ge 0
which I wish is to permit all the ipv6 routes,
but the running information becomes "ipv6 prefix-list abc permit ::/0" which only matched the default ipv6 routes
what is wrong with meHardware > Version > 5.1
Don't forget to test it on real hardware. There should be plenty of iOS 5.1-limited devices available real soon now. Keep one of those for testing. -
what is difference between distribution list and share point group? Can we add distribution list into person and group column of share point list?
there is a workaround you can try, create audience and add DL to them and deal with the audience or convert DL to groups
