Subject: ISDN Backup link and OSPF neighbor formation
Importance: High
Scratching my head on this one,.... (Reference SE Pracrice Lab V1.0GG) the
one with routers named Sleepy, Grumpy....etc.
Here is my dilemna: Sleepy (r2) has parallel links (FR and ISDN DDR) to
Grumpy (r1) ALL interfaces are defined in OSPF area 0. BRI0 on Sleepy is
configured to backup Ser0 in case of link failure. I have that part
functioning.... I shut down the FR intf and the BRI kicks into action.
What is NOT happening is OSPF routing info exchange across the Backup link.
Sh ip ospf nei goes to INIT.... and never gets to full. What am i
missing?????
Thanks in advance!!!
phil
