I have set up a simple lab:
router A - 7200 IOS 12.2(27) JS
router B - 2611
There is a serial link between A and B.
On A the serial interface is in VRF.
The B router has no VRF - just ordinary IP.
I am trying to set up eBGP between them.
But the session does not start.
The A config:
ip vrf v2
rd 7:2
route-target export 7:2
route-target import 7:2
!
ip cef
!
interface Serial2/0
ip vrf forwarding v2
ip address 192.168.25.5 255.255.255.0
!
router bgp 65005
no synchronization
bgp log-neighbor-changes
no auto-summary
!
address-family ipv4 vrf v2
neighbor 192.168.25.2 remote-as 2
neighbor 192.168.25.2 activate
no auto-summary
no synchronization
network 192.168.6.0
exit-address-family
!
I have done some tests:
Ping from B to A works.
Ping vrf from A to B works as well.
telnet from B to A on port 179 gets RST.
telnet /vrf from A to B on port 179 works.
Debug on B shows session establishment attempts, but
with TCP RST response.
Debug on A shows the neighbor is Idle - no attempts.
On A:
sh ip bgp nei
BGP neighbor is 192.168.25.2, vrf v2, remote AS 2, external link
BGP version 4, remote router ID 0.0.0.0
BGP state = Idle
Last read 02:03:54, hold time is 180, keepalive interval is 60 seconds
[...]
Connections established 0; dropped 0
Last reset never
No active TCP connection
I know, that I am new to the VRF stuff, but it is very basic case. What am I doing wrong?
