Hi Guys,
I am trying to configure dlsw peer between R3 & R5 using direct encap
(with pass-thru option) and peer doesn't come up. However, when I
configure peering using llc2 option the peering works. Looks like
peering doesn't come up due to capabilities mismatch. Debug shows
some encap problem. Not sure what's causing this?
Here's my config:
R3:
dlsw local-peer peer-id 20.20.3.3
dlsw remote-peer 0 frame-relay interface Serial0.1 103 pass-thru
interface Serial0.1 multipoint
ip address 20.20.12.13 255.255.255.248
ip ospf message-digest-key 1 md5 cisco
frame-relay map dlsw 113 broadcast
frame-relay map dlsw 103 broadcast
frame-relay map ip 20.20.12.12 113 broadcast
frame-relay map ip 20.20.12.14 103 broadcast
R5:
dlsw local-peer peer-id 20.20.5.5
dlsw remote-peer 0 frame-relay interface Serial1 105 pass-thr
interface Serial1
ip address 20.20.12.14 255.255.255.248
encapsulation frame-relay
ip ospf message-digest-key 1 md5 cisco
ip ospf priority 0
frame-relay map dlsw 105 broadcast
frame-relay map ip 20.20.12.12 105
frame-relay map ip 20.20.12.13 105 broadcast
