Hi,
I am seeing a weird output in the debug just for one set of target routes.
Could you say whats wrong from below ?
Problem: At "debug ip routing". 150.1.1.1 is constantly changing the
best nexthop from s0/0 <=> e0/0 of R2 on R3. This problem doesnt happen
for other routes though. (ex:150.1.6.6)
Taken from IEWB v3, lab 9, task 4.8
000528: *May 31 08:30:31.097: RT: SET_LAST_RDB for 150.1.1.0/24
OLD rdb: via 148.1.0.1, Serial1/0.302
NEW rdb: via 192.10.1.2, FastEthernet0/1
Topology:
R1 (150.1.1.1)----------(s0/0) R2 (s0/0)---------(s1/0.302)R3.
