I have recently been given a couple of 4900's to support an isolated application. This application was previously configured on 7600's with the following configuration:
interface GigabitEthernet2/1
no ip address
no shut
!
interface GigabitEthernet2/1.900
encapsulation dot1Q 900
ip address x.x.x.x 255.255.255.248
bfd interval 200 min_rx 200 multiplier 5
no shut
I saw a couple of postings that say 4900's don't support sub-interfaces. What should I do? I don't think SVI support BFD.
