Static route cleanup

Unanswered Question

User Badges:

I am going through several devices where static routes have been used and I am migrating them to EIGRP internally. I want to know of a command I can use on the routers to verify that once I remove the static route EIGRP knows about the routes and will insert them into the routing table. I am currently using

Show ip eigrp topology

But wanted to know if that was the best command or not.

I also have some devices that are connected to an MPLS provider and are using BGP so I need to know if BGP also has a route to that network once I remove the static routes.

Thanks.

Hello Bill,


>> Show ip eigrp topology

This is the best command you can use for this check unless you make the static route floating with AD 201 for example


you can filter with


sh ip eigrp topology


example:


sh ip eigrp topology 172.24.133.0/24

IP-EIGRP (AS 100): Topology entry for 172.24.133.0/24

  State is Passive, Query origin flag is 1, 2 Successor(s), FD is 1766912

  Routing Descriptor Blocks:

  172.24.128.221 (FastEthernet0/1), from 172.24.128.221, Send flag is 0x0

      Composite metric is (1766912/1764352), Route is External

      Vector metric:

        Minimum bandwidth is 2048 Kbit

        Total delay is 20200 microseconds

        Reliability is 255/255

        Load is 255/255

        Minimum MTU is 1500

        Hop count is 2

      External data:

        Originating router is 172.24.128.65 

        AS number of route is 0

        External protocol is Static, external metric is 0

        Administrator tag is 0 (0x00000000)

  172.24.128.217 (FastEthernet0/0), from 172.24.128.217, Send flag is 0x0

      Composite metric is (1766912/1764352), Route is External

      Vector metric:

        Minimum bandwidth is 2048 Kbit

        Total delay is 20200 microseconds

        Reliability is 255/255

        Load is 255/255

        Minimum MTU is 1500

        Hop count is 2

      External data:

        Originating router is 172.24.128.65 

        AS number of route is 0

        External protocol is Static, external metric is 0

        Administrator tag is 0 (0x00000000)



you can use sh ip eigrp topology


b)


sh ip bgp


before and after static route removal:  hint if you use the network command in BGP you should be fine if you redistribute EIGRP into BGP as discussed in other threads you should be fine also


Hope  to help
