Hi, I have a router that is not learning the default route from its neighbor
RTR2#sh ip route | i 0.0.0.0
10.0.0.0/8 is variably subnetted, 375 subnets, 11 masks
EIGRP topology topology is showing the default route though:
P 0.0.0.0/0, 1 successors, FD is 288000, tag is 22252
via 10.131.255.2 (288000/285440), FastEthernet0/0 !!!!switch connected here, <==> primary upstream router running EIGRP
via 192.168.148.45 (2182656/260096), Serial0/0/0 !!!! RTR2 upstream router connected here
I found some articles mentioning
router eigrp 23
clear ip eigrp 1 neighbors soft
clear ip route
but not sure exactly what to use. Please let me know if you have any suggestions to correct this issue.
Check the following in your configuration of which ever EIGRP neighbor is advertising the default route.
Make sure you don't have any distirbute-lists or ACLs blocking anything. Also, check to make sure if you have 'default-information originate' command configured, that you actually have a default route in your routing table, otherwise it will not advertise a default route. You can also use 'default-information originate always' if you don't have a default route configured in your routing table, but want to advertise a default route.
Hey sindan, have you done any debugging while you were clearing the routing table ?
I also had the same issue, but on virtual device, in GNS3, and it solved only after I cleared the adjacency.
No I did not do any debug while clearing the routing table. Same issue on a 3750 switch translates into bug (CSCte6976)... seems to be a code version issue where the router is not getting the default route from the EIGRP topology table into routing table.
