Hi folks... Sorry for the long message but wanted to share what was causing this problem...
We have two T1's - each connected to a separate 8 port T1 card on the 6500. We were trying to do multilink across the two cards and it obviously doesn't work (or at least with our config). Moved both T1's to the same card and everything is now fine. Just an FYI in case someone else runs across this..;) Paul -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Stewart Sent: Thursday, June 12, 2008 8:59 PM To: 'Eric Cables' Cc: [email protected] Subject: Re: [c-nsp] Multilink Routing Problem Thanks. Here's the OSPF config from the 6500: router ospf 1 router-id xx.xx.98.184 log-adjacency-changes redistribute connected subnets tag 116661016 redistribute static subnets tag 116661016 network xxx.xxx.227.0 0.0.0.7 area 0 network xx.xx.246.16 0.0.0.7 area 0 network xx.xx.64.48 0.0.0.7 area 0 network xx.xx.64.56 0.0.0.7 area 0 .......more..... Everything else connected to this device works. actually, I just checked from our core devices and the point to point /30 and the statically routed /29 are both in the routing tables: dis1-rtr-pt#sh ip route xx.xx.120.202 Routing entry for xx.xx.xx.202/32 Known via "connected", distance 0, metric 0 (connected, via interface) Redistributing via ospf 1 Advertised by ospf 1 subnets tag 116661016 Routing Descriptor Blocks: * directly connected, via Multilink1 Route metric is 0, traffic share count is 1 dis1-rtr-pt#sh ip route xx.xx.120.201 Routing entry for xx.xx.120.200/30 Known via "connected", distance 0, metric 0 (connected, via interface) Redistributing via ospf 1 Advertised by ospf 1 subnets tag 116661016 Routing Descriptor Blocks: * directly connected, via Multilink1 Route metric is 0, traffic share count is 1 Now, my question is why is the far end point to point IP showing as a /32? We have a static route to send the /29 to the "far end" and it looks fine: dis1-rtr-pt#sh ip route xx.xx.120.232 Routing entry for xx.xx.120.232/29 Known via "static", distance 1, metric 0 Redistributing via ospf 1 Advertised by ospf 1 subnets tag 116661016 Routing Descriptor Blocks: * xx.xx.120.202 Route metric is 0, traffic share count is 1 The /32 is throwing me off though.??

Is this all part of area 0, or is it configured as a stubby network? If it's stubby, you may need to configure it as NSSA to get the redistributed routes back into area 0.

It's redistributing routes via OSPF to the rest of our network but for some reason not the multilink IP address.. Anything make sense about this? I can ping the local 6500 interface from anywhere in our network but not the 2621 end (except when on the 6500). #sh ppp multilink Multilink1, bundle name is dis1-rtr-pt Endpoint discriminator is dis1-rtr-pt Bundle up for 06:32:41, total bandwidth 3072, load 1/255 Receive buffer limit 24000 bytes, frag timeout 1000 ms 0/0 fragments/bytes in reassembly list 0 lost fragments, 22 reordered 0/0 discarded fragments/bytes, 0 lost received 0xF19 received sequence, 0xC3E sent sequence Member links: 2 active, 0 inactive (max not set, min not set) Se0/0, since 06:32:41 Se0/1, since 06:32:37 No inactive multilink interfaces Originally we had OSPF on both sides of the link and the OSPF session would come up no problem as "point to point" .. Confused, we moved to static routing to try and prove this out. Is there something special you have to do to get a multilink bundle redistributed in OSPF??
