Route Table refresh

Hi All,
Do you know if it is possible to tweak the time it takes to refresh the routing table when a route changes? Is there a reg key for this? I think by default it seems to be 10 mins or so before it works out the new route.
Cheers,
Simon.

I am aware that Windows has a Dead Gateway Detection in TCP/IP: http://support.microsoft.com/kb/128978
This makes Windows identify if a Gateway is still functional.
Otherwise, manual configuration changes on TCP/IP make immediate updates on your routing table to make changes.
Not sure what are the other scenarios that are interesting you but I am not a way about a setting to tweak automatic refreshes or checks.

Strange IP's in routing table

I have a Linksys RT31P2 wired VoIP router that connects to my cable modem directly. Since there are more than 3 computers that link up to the internet in my house I have connected a Netgear FS105 5 port switch which all of the computers on my network connect to. I have had this setup for about 4 years now and it has been working fine until recently. I noticed that my connection was slowing down and wierd things were happening like links popping back to the page the link was on instead of the link itself and super long periods between page refreshes. So out of the blue I log into the router admin space and have a look around, nothing unusual. I open the routing table and I was surprised to see all of these strange Ip's, complete with their own subnet masks and default gateways. Also, all of them had a hop count of 165. The ip addresses resolved to several different ISP's in the sout eastern part of the country. Turning the router off and then back on clears all of these out but within a few days they are back. I have checked all of the computers in the network but have found nothing out of the ordinary. What is going on here? I didn't think that an attacker could come through the router firewall on a wired router but if hackers can get into top government networks, I guess they could get through a simple router. The following link is to a pic of the routing table with all of the strange entries. Anybody ever experience this and if so, what was done to prevent it from happening? Thanks.

I'm not sure I follow exactly. Are you saying a firewall between the router and modem? Doesn't the router already have one in place and is there such a thing as a firewall box that goes between devices like that? Somebody told me that this might have been due to p2p sites like Limewire or Bearshare, neither of which my wife nor myself use. My daughter has used Limeware but not much from what she says. I don't know but I really would like to fix this for good.

The growth of the internet routing table + LISP

I have been challenged with the task of putting together a 15-20 minute presentation of how I might go about solving the problem of the growth of the internet routing table.
If I am understanding the question correctly - as the internet grows so will the number of IPv4 and (moreso) IPv6 prefixes that appear in the global internet routing table. This will mean that the PE and P routers in a Service Provider network will find themselves having to deal with more prefixes that will in turn increase the possibility of bogons interferring with proper routing and increase the load on the routers themselves.
Besides being a very open ended question, I am trying to look at it from the perspective of a Service Provider (whom I work for) and have come up with the following options (admittedly this is only after a quick google on the topic):
> Improvise in the short term by adjusting CAM table allocation
> Use selective hearing by filtering prefixes that are not important
> Use external assistance like LISP and DNS
> Spend Money and upgrading existing routers to handle the load
Obviously with only a 20 minute window I cannot talk about much and I would like the options to be innnovative and interesting. LISP seems like an interesting option and I would like to learn about it - however I am having trouble tracking down resources that give a basic introduction to exactly what and how LISP works (every time I try and search for it a get pushed to sites talking about the programming language ).
So this leads me to two questions:
1. Is there anything important, vital or interesting that I have not included in my quickly put together list above.
2. Is anyone aware for a good site/resource that explains LISP from a beginners/tutorial-type perspective.

How to count number of default routes in routing table

Is there a way for java to count the number of default routes in the routing table?

Hi Sathish,
If you are using table mean surely you are binding the table to some model like JSON model. You can bind the checked value of the column with the checkbox in the template. So while checking you can directly check the property by taking the reference from the model. Navigate through all the objects in the model and check the property you wanted.
This is the logic I have used to get the checked property form the table column. My table id is "tableId" and it is being binded with "/tableModelData" of json model.
var myModel = sap.ui.getCore().getElementById("tableId").getModel().getProperty("/tableModelData");
for(var i= 0 ; i< myModel.length ; i++)
var singleObject = myModel [i];
if(singleObject.checked == true){
your logic.

How to avoid table refresh on row selection

Hi,
I have a table where the row selection happens on selecting the check box in the first column of the row. The check box is bound to the transient Boolean attribute of my VO to support this functionality which is missing in new version of ADF. The selection is working fine, however I am facing the issue with table refresh. Everytime I click checkbox to select or unselect a row my whole table is getting refreshed which is very unusual for user point of view. This is my code for the checkbox column:
<af:column sortProperty="isSelected" sortable="true"
headerText="#{bindings.pricingObjects.hints.isSelected.label}"
id="c4"
inlineStyle='#{(row.isSelected)?"background-color: #E7E7E7":""};'>
<af:selectBooleanCheckbox value="#{row.bindings.isSelected.inputValue}"
required="#{bindings.pricingObjects.hints.isSelected.mandatory}"
shortDesc="#{bindings.pricingObjects.hints.isSelected.tooltip}"
id="it4" simple="true"
autoSubmit="true">
<f:validator binding="#{row.bindings.isSelected.validator}"/>
</af:selectBooleanCheckbox>
I have to keep autoSubmit="true" on selectBooleanCheckbox because the table has to change color of the row everytime the checkbox is selected or deselected. Also, there are multiple commandToolbarButton such as "Delete" which needs to be enabled/disabled depending on the row selection.
Is there anyway, I can achieve this behaviour with minimal refresh of table?

Hi Marge,
Yes I do have Add and Delete toolbar button in the panelCollection and also set partialTrigger="tableId" on them. I need this partialTriggers because Delete button should enable/disable depending on number of rows added in the table. However, I tried removing them but it did not work for me, table is still refreshing. BUT this solution does work in combination of other solution i.e. removing ChangeEventPolicy="ppr" on the iterator. I need ppr because I have a form which is bound to the same iterator and should change on table selection. The design is like this,
- Read-only Table on top
- Editable Form below
- Select the row in table and edit the fields in the form
If I remove ppr then my form is not updating with the row selection.

Afroz

Eem script monitor routing table - multiple entries into 1 email

I have the following script running to report on routing table changes
event manager applet route-table-monitor
event routing network 0.0.0.0/0 ge 1
action 0.5 set msg "Route changed: Type: $_routing_type, Network: $_routing_network, Mask/Prefix: $_routing_mask, Protocol: $_routing_protocol, GW: $_routing_lastgateway, Intf: $_routing_lastinterface"
action 1.0 syslog msg "$msg"
action 2.0 cli command "enable"
action 4.0 info type routername
action 5.0 mail server "10.*.*.*" to "roger.perkin@****" from "Switch1" subject "Routing Table Change" body "$msg $_cli_result"
It works perfectly however if multiple routes change I get multiple emails.
Last night we had a site go out and I got about 20 separate email for each subnet change.
What I would like to do is get this script to take all routes changed in a 1 minute interval and then output them into an email.
Not quite sure how I would go about that?
Thanks
Roger
Currently studying for my CCIE and just started on EEM, have not done much scripting before so this is all good stuff to know.

You can't do this with one policy. However, you could accomplish this with a timer policy that will batch up the pending updates, though. Something like this would work.

VPN connection created with CMAK fails to update routing table on Windows 8.1 with error 8000ffff

When my clients connect their CMAK-created VPN, it fails to run the script to set their routing table with the following error:
Custom script (to update your routing table) failed (8000ffff)
My objective is to create a VPN connection with split tunneling - does not use the VPN connection as the client's default gateway.
All my clients are on Windows 8.1 64-bit, and are logged in with Administrative privileges
My VPN Clients are on 10.242.2.0/24, my internal network is on 10.172.16.0/24
I want only traffic for 10.172.16.0 to go via the VPN. Everything else should go via the client's internet connection
My Connection Manager Administration Kit profile, was created on Windows 2012 R2 CMAK with the following settings:
"Make this connection the client's default gateway" is UNticked on the IPv4 tab.

+++ End of txt file +++
The txt file is saved in DOS/Windows format (not Unicode or UTF-8 which I've read causes problems)
I've tried everything in lower and upper case in the txt file after reading that the file might be case sensitive

That was it. Thanks, Steven
"By default, the dial-up entry and the VPN entry have Make this connection the default gateway selected.
Leave this default in place, and remove any gateways by using the REMOVE_GATEWAY command in the routing table update file itself."
It seems counter-intuitive to leave
Make this connection the default gateway selected, when I specifically don't want that behaviour, but leaving it selected and using REMOVE_GATEWAY works for me.

VRF Best Practice: LAN only VRF, Mgmt VRF, Global Routing table or VRF?

I am setting up a routed LAN (not a WAN) environment on two 6500 switches (sup-720). My goal is to create 32 routed environments separated by logical firewalls (multi-context ASA's). So I want a âcoreâ router in each environment, and don't want to buy 32 pairs of 6500's-sorry Cisco.
Each of these environments are tied together by a core routing environment, running on the same pair of 6500's. No WAN MPLS is going on and I am trying to use VRF for each of the routed environments core router. The management functions of the 6500 shall run off the VRF Core router and ip range (the one that ties all the other VRF's together. Here is a simple diagram:
VRF1
||
FW1
||
VRFCOR
||
FW2
||
VRF2
So to go from VRF1 to VRF2, you traverse two firewalls and VRFCOR.
Several questions related to this design:
1) Am I nuts to use VRF's in this application?
2) Is there a better choice than VRF's to do what I want?
3) Should VRFCOR be the global routing table (IOW, not a VRF)? Or should be its own VRF? Another way to ask this is: Shall a router ever run entirely in VRF tables, or should there be at least one global table in use?
4) Are there problems with any management protocols on a VRF, such as NTP, AAA, SNMP, LOGGING, TELNET? Or have all those been worked out?
5) Any other suggestions?
TIA, Will

VRF is suited for such kind of an application. Refer to URL http://cisco.com/application/pdf/en/us/guest/netsol/ns171/c649/ccmigration_09186a0080851cc6.pdf to get an idea about the

How to use "Routing Table" option in Proxy service in OSB ?

Hi,
I have created Business and Proxy services in my OSB console. I have used "Custom Query" option while creating the Database Adapter and I'm passing one input parameter to the query. My input parameter is "Name".
Based on the input values for this parameter, I need to pass a corresponding values to the query. For example, If I pass the following values to "Name" input parameter (India) I need to pass "Value1" to my query -
India --> Value1
China --> Value2
America --> Value3
To achieve this requirement, I have used "Routing Table" option. I have specified the values as follows -
Expression - $body/fet:FetchCustDataInput/fet:Name
Operator- '='
Compare value - India
Service - "My Webservice"
Operaton- "My Service Operation"
In the "Request Actions:" I have added the "Add an Action --> Messaging Processing --> Replace" and provided the following values -
Replace <XPath> = $body/fet:FetchCustDataInput/fet:Name
in Variable = "Name"
with Expression = xs:string('Value1')
and selected "Replace node contents" option.
No validation errors I faced. I have created the Routing table in Proxy service. But when I try to execute the proxy service in my Test Console, I get the following error message -
"The invocation resulted in an error: Unknown error while processing message for service ProxyService OSBQueryService/FetchByCustomQuery/FetchByCustomQueryPS."
I have even enabled "Direct call" and "Include Tracing" options as well. The message under "Tracing" give "(echoing request)
Routed Service. No Service has been invoked, the request is echoed.".
Can anyone please help me to resolve this issue.
Thanks in Advance,
Udaya

Did you put any loggers in the proxy at request pipeline prior to route node ? Can you trace if the request has entered request pipeline aleast.
If not just check the transport headers under the request window in the test console. There should be a text box for entering username/password which should be left blank. I have faced this unknown exception from test console in some browsers where an incorrect username/password used to get populated here. Check this ..

SMTP routing table does not seem to be working correctly.

Why isn't the SMTP routing table working properly?

First, make sure you have the routing table setup correctly.
Entries in the Routing table are in the following format:

<incoming recipient domain>:<route to this host>

For example, if you want all mail addressed to [email protected]
to be routed to mailhost1.realdomain.com, you would add the following
line to the SMTP routing table:

virtualdomain.com:mailhost1.realdomain.com

With the above option, any mail coming in addressed to <anyone>@virtualdomain.com
will be routed to mailhost1.realdomain.com. The recipient email
address will not be re-written, so mailhost1.realdomain.com needs to
accept mail addressed to the original address, @virtualdomain.com,
even though it is in realdomain.com.

Before adding, changing or deleting any SMTP routing table entries, double-check
with the DNS Administrator that the host names you specify are valid,
registered host names. If in doubt, you can use IP addresses for the
"route to" host, but not for the "incoming recipient domain".

Wild cards can be used in mail routing table options, but they indicate that a
hostname will fill that spot. For example:

*.domain.com:mailserver1.domain.com

In the above example, any mail addressed to <anyone>@<anyhost>.domain.com
will be routed to mailserver1.domain.com. However, mail addressed to
<anyone>@domain.com will not be routed. To fix this, add this
line:

domain.com:mailserver1.domain.com

Note: You cannot use the SMTP routing table to route all mail
addressed to a specific domain to a specific account. You would need to use
a "Mail Pool" account for this, which is only available in Messaging Server
3.5+.

is this entry valid for routing table in nms v 4.15 p6
* : anotherhot.mydomain.com:5000
assuming that my anotherhost is listening and accepting on port 5000 for smtp connections. and i wanna forward all the mails to that host

How to add a route in routing table

Hi,
I want to add a new route to the routing table to get access to a explicit tunnel. Using Terminal I tried
route add 172.16.0.0 mask 255.255.0.0 192.168.0.102
route: must be root to alter routing table
so I tried:
sudo route add 172.16.0.0 mask 255.255.0.0 192.168.0.102
To proceed, enter your password
My password ist enmpty. But I see the message:
Sorry, try again.
Is there a better way to add a route to the actual routing table?
How can I reset my root-password?
Thanks & best regards,
Torsten

Difference between sh ip bgp & sh ip route? BGP tables and main routing table.

Difference between sh ip bgp & sh ip route?
sh ip bgp :::: loc-rib ?
sh ip bgp nei x.x.x.x advertised-routes : adj-rib-in.
sh ip bgp nei x.x.x.x recieved-routes : adj-rib-out.
sh ip bgp nei x.x.x.x routes : loc-rib ?
sh ip route = rib ? if yes does it mean its loc-rib ?
so in a given router with bgp running, will there be 5 tables (sh ip bgp; adj-rib-in; loc-rib;adj-rib-out; sh ip route) ? if yes where are they saved ?

sh ip bgp
shows the BGP table (where are stored info coming from BGP update)
sh ip bgp nei x.x.x.x advertised-routes
shows networks that your router will advertise to a specific neighbor
sh ip bgp nei x.x.x.x recieved-routes
shows advertisement received from a specific neighbor; networks (NLRI) filtered with route-map distribute-list,... are included (Inbound soft reconfiguration must be enabled)
sh ip bgp nei x.x.x.x routes
shows only routes sent by a specific neighbor and not filtered or discarded (i.s accepted)
sh ip route
show routing table; it contains the best route for each network (best is first of all the lowest administrative distance, then the lowest metric)

Managing routing tables in Windows

Hi,
I need some help regarding manipulating routing tables in Windows through JAVA. what i am looking for are functions in java that i can use to make changes in the OS (windows) routing tables so as to provide facilites like forwarding, routing etc to the various packets on the basis of their destinations (and may be source)
Can anyone give me some pointers regarding that?
Thanks in advance.
Amitabh

Maybe you can use the Runtime class to actually call
Windows' exe "route.exe" and use route.exe's
arguments to specify what you needs.

Naming Networks in EEM route table monitor

I have the following EEM applet running on one of my core devices to monitor any changes in the routing table.
event manager applet route-table-monitor
event routing network 0.0.0.0/0 ge 1
action 0.5 set msg "Route changed: Type: $_routing_type, Network: $_routing_network, Mask/Prefix: $_routing_mask, Protocol: $_routing_protocol, GW: $_routing_lastgateway, Intf: $_routing_lastinterface"

action 4.0 mail server "*.*.*.*" to "roger@*********" from "Core1" subject "Routing Table Change" body "$msg $_cli_result"
action 8.0 set msg "Route changed: Type: "
This works brilliantly however the email I get lists the networks by IP and I am trying to get it to identify them by name
Email Output
Route changed: Type: modify, Network: 10.8.4.0, Mask/Prefix: 255.255.255.0, Protocol: BGP, GW: 10.1.1.1, Intf: N/A
The script is running on a 3750
I tried putting ip host info on the switch but that did not work.
I am not sure if there is an extra line I can add to the script or if anyone else has done this?
Thanks
Roger

I don't understand the request. Where would the network "name" come from? Networks are unnamed on IOS.
