Re: [c-nsp] BGP neighbor not establishing session

I'd suspect MTU issues here. Cheers, Mark. It's looking like it somehow might be related to that. For a test, we set the mtu on the toro-router2's interfaces back to 1500 from 9216. After that was done, the sessions to the vanc routers both came up! Strange because we didn't change any of the

Well, we upgraded from 7206VXR NPEG1s to 7301 but the software went from 12.3(26) to 12.2(33)SRE1 as well. The interfaces on both sides are all set to 9216 mtu but the path between them is a lot less than that. Another thing that a colleague of mine pointed out was that the distance between t

[c-nsp] BGP neighbor not establishing session

I've tried searching around for this problem but haven't found much info. We upgraded some 7301 routers the other night and there are a couple of neighbors which have not been able to re-establish themselves. Debugging from one of the routers shows this: Nov 21 21:06:51.902 EST: BGP: Neighbo
