VRF & EIGRP Routing

[zekebashi]

Hello,

I setup a GNS3 lab to test VRF and EIGRP routing. It's a simple lab where I have two switches(VSS_Dist1 & Core1). Both have VRF SharedVRF, SVI 992, which is in VRF SharedVRF, and EIGRP 900. I advertised network 172.26.90.0/24 on both EIGRP processes on both switches. Both switches established EIGPR relationship; however, there's no entries for the any routes advertised through EIGRP. See config below.

Why can't I ping the SVI of each switch? Also, why isn't EIGRP advertising the networks of the interfaces I included in the EIGPR process?

Thanks in advance.

Hi Zekebashi,

1. Ping you initiated to test the connectivity should work without EIGRP also. There is something else which is blocking this ping. "debug ip icmp" output may help to identify the direction of the problem.

2. If you have route via EIGRP and via directly connected, you will never see it via EIGRP in route table.

3. You must enter command "show ip eigrp vrf SharedVRF topology" to check them. Output will look like below.

#sh ip eigrp vrf SharedVRF topology
EIGRP-IPv4 Topology Table for AS(900)/ID(172.26.90.17) VRF(SharedVRF)
Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
       r - reply Status, s - sia Status

P 172.26.90.16/29, 1 successors, FD is 281600
        via Connected, Vlan992.
