[c-nsp] OPSF - VRF Problem

[Peter Rathlev]

Hi Anton,

Configure an interface for router-id (e.g. a loopback) before doing the
OSPF configuration:

ip vrf A
 rd 64512:100
 exit
!
interface Loopback100
 ip vrf forwarding A
 ip address 10.0.0.1 255.255.255.255
 no shutdown
 exit
!
router ospf 10 vrf A
... etc.

That should work.

Regards,
Peter
