Hi guys, Hoping to pick someone's brain about this issue that we're seeing:
We have two 6509 Cat switches with a Gig trunk and RSM's. Multiple VLAN's are configured on the RSM and we are running OSPF (area 0). The problem we have is that the two 6509's are forming OSPF adjacancies with each other on every vlan (via the Gig trunk). So if we have 4 vlans set up there are 4 sets of OSPF neighbor adjancies set up, for example: Neighbor ID Pri State Dead Time Address Interface lo-3.bob 1 FULL/DR 00:00:38 192.168.1.140 Vlan1 lo-3.bob 1 2WAY/DROTHER 00:00:32 192.168.1.172 Vlan30 lo-3.bob 1 2WAY/DROTHER 00:00:32 192.168.1.188 Vlan35 lo-3.bob 1 FULL/BDR 00:00:37 192.168.1.34 Vlan100 [The names and IP addresses have been changed to protect the innocent!] The same is also true on the partnering router "Bill". Now, in reality, there are about 10 or 12 vlans in this setup, most of them are passive interfaced so they do not add into the equation. We can't passive interface these vlans because they are used for distribution to different OSPF areas. My question is this, how can we ensure that bob and bill only form one adjacancy with one another, not one per vlan. We were hoping to do something like a "source-interface" whereby you specify that OSPF adjacancies are formed on a given address (eg a loopback int), that way regardless of how many vlans bob and bill can see each other on, they will only form adjacancies on one IP address with one another. Any comments or suggestions would be greatly appreciated. (Here's were it's something REALLY obvious and I look silly)...
