Hi Guys,

 

When I configure a neighbor under the OSPF process that is not part of one
of the networks that OSPF is running on, it causes the router to crash and
reboot. anybody seen this before?

 

 

Rack6R5#sh run | beg router osp

router ospf 1

 router-id 150.6.5.5

 log-adjacency-changes

 network 150.6.5.5 0.0.0.0 area 0

 network 183.6.0.5 0.0.0.0 area 0

 network 183.6.45.5 0.0.0.0 area 45

!

Rack6R5#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Rack6R5(config)#router os 1

Rack6R5(config-router)#nei 1.1.1.1
