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: $_routing_lastinterface"
action 1.0 syslog msg "$msg"
action 2.0 cli command "enable"
action 3.0 info type routername
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.

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 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.

I have a server with Intel 82576 Gigabit Dual Port Nics. I have configured them to use iSCSI boot the primary looks to 10.0.0.1/24 and the secondary looks to 10.0.1.1/24. The target is configured correctly. Everything boots as expected.
I have added the MPIO feature and configured MPIO for the iscsi initiator as per: http://blogs.technet.com/b/migreene/archive/2009/08/29/3277914.aspx.
My issue is that the iSCSI networks show up in the routing table like so:
I did not configure a default route in the Intel setup utility:
I tried to explicitly remove the 0.0.0.0 entry and leave blank, with no change. As you can see with the above routing table traffic attempts to travel over these routes:
C:\Users\Administrator>ping google.com

Ping statistics for 209.85.145.99:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
A ping to the outside world first attempts on 10.0.0.x/24 network, then on 10.0.1.x/24 network and then finally on the network the traffic should go over. I don't want my iSCSI traffic to ever show up with a default route. How do I get rid of it?
route delete 0.0.0.0 mask 0.0.0.0 "on-link" results in: The route deletion failed: The parameter is incorrect.
route delete 0.0.0.0 mask 0.0.0.0 on-link results in: The route deletion failed: The parameter is incorrect.
route delete 0.0.0.0 deletes all default routes, then I have to add back in the "valid default route" of 192.168.100.6.
I would like to not have to do a route delete though.So I've sort of given up on fixing the gateway assignment in the route for iSCSI boot. I configured a DHCP server to give out the information required by iSCSI boot and configured the network cards to use DHCP for their configuration. I insured
that my DHCP server gave out no default gateway entry. However, I still got the undesired routes in the routing table. This makes me assume that there isn't a "fix" for it, only the workaround.
Here is the script I run on each iSCSI Boot initiator (you would obviously change the ip number to suit your environment):

Syslogging routing table updates
I have a stable network that rarely has any routing changes. I would like any routing table updates to be sent to a logging server or possibly generate a trap so I am aware of the changes. Currently I use a Debug ip routing command and get the output sent. Is there another way to accomplish this without using the debug command?
KeithThis will depend on your version of IOS. Newer versions of IOS include the Embedded Event Manager version 3.0. This version of EEM includes a route table event detector that can be used to spot routing updates. You can try something like this:
event manager applet routing-changes event routing type all network 0.0.0.0/0 ge 1 action 1.0 syslog msg "Routing table changed; Type: $_routing_type, Network: $_routing_network, Mask: $_routing_mask, Protocol: $_routing_protocol, Gateway: $_routing_lastgateway, Interface: $_routing_lastinterface" -
Network Manager Role - route add/delete command
How to establish role (RBAC) to modify routing table ? When I use embeded Network Management profile for this purpose, after running route add command I receive message that running route command needs root priviledges.
Could explain in more details ?
What I want achieve is to give some users ability to modify routing table. For that purpose I established role named service. I have assingend built in profile Network Management to that role via SMC. I established also right profile named Service Commands with /usr/sbin/route command. But when I am trying modify routing table I receive the following error:

Activating failover config drops routing table
I'm attempting to configure two ASA 5520 for active/standby failover.
When I enter the “failover” command to enable the config on the primary ASA, the entire routing table disappears.
There is no routing process running, only static routes are configured.
Is this an expected behavior of the failover process and if so, how long should I wait for the routes to come back?
Is there a document somewhere explaining this behavior?
I’ve searched all day but couldn’t find anything that came close to explain this.
If this is not normal, what could be causing this to happen?
ThanksOriginally, both primary and secondary were configured for failover.
At this point I'm only trying to understand why the rounting table is cleared so the secondary is turned off.
Is it an expected result to have your routing cleared when you enable failover?
I've waited only ~30 seconds for the routes to come back. Maybe I'm not waiting long enough, but I haven't seen in all the documents I've read that lost of traffic should be expected when Failover is enabled.

Environment variables for use with EEM routing trigger?
I've only recently started looking into EEM, and was hoping a guru here could clear something up for me:
The docs do not show there to be any environment variables that can be used with EEM's "routing" trigger, to determine which route was added, changed, or modified.
It seems odd that the trigger would allow you to fire specifically on adds or removes, but then give you no indication of the specific route that was added or removed. Is this info in some non-obvious generic variable?
Or, is the only available approach to cache the route table, and then parse the whole table when the event fires? I haven't seen any examples that use this trigger; maybe because of this lack of any documented routing-specific variables?
Thanks in advance!Every event detector has its own set of internal variables. These are different than environment variables. Environment variables are those you can modify in the config with "event manager environment". If you have a device which supports the routing event detector, you can run the command, "show event manager detector routing detailed" and that will show you all of the available internal variables.
I actually did a programmatic applet example using the oruting ED for my Networkers session this past year. This example doesn't use any of the internal variables, but it will give you an idea of how this ED works:
event manager applet route-watch
event routing network 10.1.1.0/24 type add protocol ospf
action 001 cli command "enable"
action 002 set done 0
action 003 while $done eq 0
action 004 wait 5
action 005 cli command "ping ip 10.1.1.1"
action 005 regexp "!!!!!" "$_cli_result"
action 006 if $_regexp_result eq 1
action 007 cli command "config t"
action 008 cli command "int Tunnel0"
action 009 cli command "shut"
action 010 cli command "end"
action 011 set done 1
action 012 end
action 013 end
This applet will be triggered when the route 10.1.1.0/24 is learned via OSPF. The applet will then try and ping 10.1.1.1, and when it is 100% successful, it will take down the backup tunnel interface. Because it may take a little while before the ping is 100% successful, the applet will loop until it gets a 100% success (or until the 20 second maxrun timer expires). -
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.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.

Why Do I have A Volume Named Network On My Desktop -- What Did I Do
I noticed yesterday that I have a volume on my Desktop named "Network". here was also an icon called Server", but that disappeared after I restarted. "Network" may have been there 2- 3 days ago, but I'm sure it wasn't there before 3 days ago. No other users on the machine have it. I can't unmount it. Where did it come from?
I am running OS 10.4.10 on an iMac G3. I normally connect to the internet via ethernet. I have a cable modem and the line from the modem goes to a wireless router. My computer is connected via ethernet from the router to my Mac.
The other day I disconnected my ethernet and tried to connect wireless. It seems to accept the password, but I could not connect. I never had a problem before.
Other details:
I have tried restarts and complete shut down with no affect.
I start-up from an external firewire hard drive. When I start up using the internal "iMac 40G" drive, the Network volume does not appear.
I haven't added or deleted any items from my account's list of Login items.
Internet Sharing is Off; Firewall is On with Network Time the only checked item (which it has been for years); Personal Fire Sharing is off with no items checked.
I'm don't have a lot of networking knowledge, although I do understand some terminology.
Any assistance will be appreciated.Thanks, but still is not resolved. My Finder prefs didn't have show the Network Icon in the sidebar. I tried toggling it on and off anyway.
I logged in as root user. The Network icon is on the root desktop. but it is an alias. The original is Home. I could trash the folder Library which is shown when I open Network; it also was an alias. But when I tried to trash the alias "Network", it wouldn't let me because I "don't have sufficient privileges".
When I login with my normal ID, the icon is not an alias -- it is a volume. I can't trash any part of it. Get Info shows server address as nfs://automount%29-nsf%20%5B143]. My permissions are I can read only; owner is system with read and write access; group is wheel with read only access; others can read only. -
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.
Define a routing table update is specified with a text file containing:
+++ Start of txt file +++
REMOVE_GATEWAY
add 10.172.16.0 mask 255.255.255.0 default metric default if default
+++ 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

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. -

Help required. I don't want to use NetworkManager.The following might be useful:
https://access.redhat.com/solutions/783533
"When transitioning from NetworkManager to using the network initscript, the default gateway parameter in the interface's ifcfg file will be depicted as 'GATEWAY0'. In order for the ifcfg file to be compatible with the network initscript, this parameter must be renamed to 'GATEWAY'. This limitation will be addressed in an upcoming release of RHEL7."
NetworkManager is now the default mechanism for RHEL 7. Personally I don't quite understand this, because as far as I can gather it is a program for systems to automatically detect and connect to known networks. I think such functionality can be useful when switching between wireless and wired networks, but for a server platform, I wonder. -
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)

Database tool for routing table history changes
Dear Community, I'm looking for a freeware tool to hold history changes in routing tables for small to medium network running BGP, OSPF and MPLS VPN routing tables via VRFs. This tool need a way to compare the database in order to know if these are the same during the time.
Is there a way to do this in Cisco Works?
Thanks in advances for your recommendations.Julius,
There are no industry recommended open source DB tools.
Normally it depends upon the developer preferences that how he/she wants to see the tool usability.
I can suggest you to go through the below link:
http://sourceforge.net/search/?type_of_search=soft&words=SQL+Tools
You can find many open source SQL tools, which you have to test and select one among them.
I can suggest you to use:
1) TOra
2) Easy SQL
3) SQuirrel

Best of Luck -
Route not showing up in routing table.
I have my core switch connecting to my router which connects to our MPLS provider. My router has a BGP default route going to the MPLS provider edge router B* 0.0.0.0/0 [20/0] via 172.30.252.78, 1w4d .... This route is not showing up in my core switch. Shouldnt it show up as an eigrp ex default route? Can anyone assist me? my routing table for each device is below. Thank you!

The core switch has got a static default route pointing to 10.192.61.1. It has got a better AD value than the EIGRP routes.
Even if you are redistributing the BGP routes into EIGRP, EIGRP default route will not make it to the routing table because of the higher AD value than the static route.
However, you can view that it the EIGRP topology table. Check 'Sh ip ei topo'.

Interface Vlan is not installed in routing table
Dear All,
Today I faced a strange problem and I want to share it with you to find what is the problem ?
we have a VRF for one customer and we use interface vlan to define customer's branch.
The customer interface is VLAN 422 and it is defined under customer VRF probably .
