[j-nsp] MX480 - BGP Session Not Coming Up

[Keegan Holley]

We migrated a trunk connection from Cisco 7206 to MX480. All the BGP session
> was up for a while & goes down. The following is the error message in MX480
> (10.2R2.11):
>
> rpd[1358]: task_connect: task BGP_remoteAS.a.b.c.d.14+179 addr a.b.c.d+179:
> Operation not permitted
> rpd[1358]: bgp_connect_start: connect a.b.c.d (External remote AS):
> Operation not permitted
>
> What messages do you get from the cisco box?  The operation not permitted
message seems out of place if no changes were made.  Does the peering come
right back up after the error happens?  Any interface flaps in the logs? Can
you telnet to port 179 from both routers?
