Hello, all. Any idea why two routers sharing an Ethernet segment
(192.138.192.0/19) would show IP networks from each other in their isis
databases, but NOT have them in the ip routing table?
E.g.:
Router A is level-1 only
Router B is level-1-2
RouterA# show isis database xx00.0800.1938.00-00 detail
IP Address: 192.178.183.13
Metric: 7 IP 200.200.200.88 255.255.255.252
Metric: 2 IP 192.138.192.0 255.255.224.0
Metric: 16 IP 192.178.183.12 255.255.255.252
etc., etc.
RouterB# show isis database xx00.0800.0938.00-00 detail
IP Address: 172.16.30.30
Metric: 4 IP 192.138.192.0 255.255.224.0
Metric: 4 IP 172.16.30.0 255.255.255.192
Metric: 0 ES xx00.0800.0938
Yet, the 172.16.30.0 network doesn't show up in Router B's ip routing
table, and 192.178.183.12 doesn't show up in Router A's ip routing table.
Do they have to advertise the "shared" network with the same metric, or
some other such restriction?
Any assistance would be greatly appreciated.
Thank you,
