Re: Route Tagging with Default Route

yeah i got it to work, needed to set my RIP to v2 and no auto-summary

i am seeing the same thing now, no tag on the 0.0.0.0 route from OSPF,
interesting it does come with a tag to my R2 router from my R1 router with a
tag of 1:

R2(config-router)#do sh ip route 0.0.0.0
Routing entry for 0.0.0.0/0, supernet
  Known via "ospf 1", distance 110, metric 1, candidate default path
  Tag 1, type extern 2, forward metric 10
  Redistributing via rip
  Last update from 10.12.12.1 on FastEthernet0/0, 00:02:30 ago
  Routing Descriptor Blocks:
  * 10.12.12.1, from 100.100.100.100, 00:02:30 ago, via FastEthernet0/0
      Route metric is 1, traffic share count is 1
      Route tag 1

from my debug it appears that the 0.0.0.0/0 route is treated the same as the
10.12.12.0/24 (in my lab that is the link between R1 and R2) and gets a tag
of 0:

R2#debug ip rip
RIP protocol debugging is on
R2#clear ip rou
R2#clear ip route *
R2#
*Mar 1 00:32:24.943: RIP: sending v2 update to 224.0.0.9 via
FastEthernet0/1 (10.23.23.2)
*Mar 1 00:32:24.943: RIP: build update entries
*Mar 1 00:32:24.943: 0.0.0.0/0 via 0.0.0.0, metric 11, tag 0
*Mar 1 00:32:24.947: 10.12.12.0/24 via 0.0.0.0, metric 1, tag 0
*Mar 1 00:32:24.947: 100.100.100.100/32 via 0.0.0.0, metric 11, tag 110
*Mar 1 00:32:24.947: 200.200.200.200/32 via 0.0.0.0, metric 1, tag 200
