Hi all,
I'm doing the ospf lab and ran across this error when trying to configure task
# 4( the backup link between R2 and R5 should be in area 25)
example of my config output:
R2
interface Serial1/0.256 multipoint
description Frame Relay Cloud 1
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
backup active interface s1/2
error message:
R2(config-subif)#backup active interface s1/2
Active backup configured on non-X.25 interface.
Active backup will be disabled till 'encap x25' is configured.
R2
interface Serial1/2
ip address 150.100.25.2 255.255.255.0
encapsulation x25
R5
interface Serial1/2
ip address 150.100.25.5 255.255.255.0
encapsulation x25
to test it out, I shut down the s1/0.256 interface...
R2(config-subif)#do sho ip int brie | exc una
Interface IP-Address OK? Method Status

How do you fix it with out breaking the frame-relay encap requirement?
