Ok. I got it to work the way I understand. The problem was that I shut R5
and R6 after removing the dlci from R2. Now the DLCIs are on R2, no EEK
configured, and when I shut R5 and R6 main interfaces, R2 subinterface goes
down:
R2#show ip int brief s0/1/0.256
Interface IP-Address OK? Method Status
Protocol
Serial0/1/0.256 150.100.100.2 YES manual down
down
R2#show run int s0/1/0.256
Building configuration...
Current configuration : 349 bytes
!
interface Serial0/1/0.256 multipoint
description Frame Relay Cloud 1
bandwidth 64
backup interface Serial0/2/0
ip address 150.100.100.2 255.255.255.0
frame-relay map ip 150.100.100.5 205 broadcast
frame-relay map ip 150.100.100.6 206 broadcast
frame-relay interface-dlci 205
frame-relay interface-dlci 206
no frame-relay inverse-arp
end
I guess the lesson is to troubleshoot one step at a time ;)
