Evening All
Having a really strange one here, where keepalive messages seem to be
getting lost between 2 MX80 routers doing external BGP to each other.
The BGP session comes up ok, and then drops 30 seconds later as the
other side does seem to be recieving the keepalive.
Now to make things more strange is I have seen this happen before
recently with another pair of mx80's one of which is talking to one of
the current pair fine.
So we have MX80's at ISP1-4
ISP1-ISP2 is having this issue, these are both running old versions of
Junos and had previously been put down to this and the link had been
given up on.
ISP2-ISP3 is working fine and has been for nearly a year
Now we have ISP3-ISP4 having the same issue. Both these routers are
running the latest version of JUNOS.
Topology of ISP1-ISP2 is
MX80 <-> Ubiquiti 10G <-> Extreme 10G <-> MX80
Topology of ISP2-ISP3
MX80 <-> Extreme 10G(as above) <-> MX80
Topology of ISP3-ISP4
MX80 <-> Juniper EX3300(virtual Chassis <-> MX80
Anyone have any ideas on this as I am drawing a blank.
Regards
