Nortel 5510 not routing with to default routes
Posted on 2014-04-23
I have a Nortel 5510 switch that is incorrectly routing information, this is the problem:
Until recently I have only had two routes from the Nortel, however after adding a new port to Vlan 2 traffic for the 10.0.0.0 subnet stopped routing to the next hop. For example If I run a traceroute to 10.16.160.2 from either subnet traffic never leaves the switch onto the next hop, although I can make this work by adding the static route 10.16.0.0 255.255.0.0 to the switch.
I have tried destroying the second Vlan and recreating it but suspect that the problem relates to a setting in the switch can anybody help.
192.168.16.0/24 GW 192.168.16.14 Vlan 1

10.0.0.0 255.0.0.0 192.168.16.3 Metric 9
0.0.0.0 0.0.0.0 192.168.16.12 Metric 10
