[c-nsp] OSPF issue

[John Elliot]

Cheers guys - It would appear that there is some filtering of ospf on this new link...I've changed both ends ints to non-broadcast, and added nei statements to ospf, and we now have adj that's been up for ~30min.

Neighbor ID     Pri   State           Dead Time   Address         Interfacexxx.xxx.76.248    1   FULL/DR         00:01:37    xxx.xxx.66.62   Port-channel1.87xxx.xxx.76.248    1   FULL/DR         00:00:31    xxx.xxx.66.2    FastEthernet3/0
Ill get onto carrier tomorrow regarding the multicast filtering.Side note - Is there any potential issues with running mpls over this link(As I dont see ldp neig on R1 for R2):#sh mpls ldp neighbor port-channel 1.87(I do see ldp nei on R2 though(via both portchan1.86 + portchan1.87))Thanks again for your assistance.....much appreciated!
