Dear Experts,
We are integrating a pair of MX480 (PE) to a Cisco based IP network and
we are having problem with VRF load balancing.We cannot ping all
connected interfaces (only some of them can be pinged) of the Cisco
routers from Juniper routers. Below are the configuration excerpts of
the routers. If we try to remove the "maximum-paths eibgp 2 " command
from cisco address family ipv4, everything works fine (all routed
interfaces of cisco are reachable from Juniper). But this command is
required by the network to load balance the VRF traffics on the two PEs
of every site. This configuration is loaded to all cisco PE routers of
the network and we cannot easily remove it from all cisco PE routers.
If you had experienced this kind of setup please share with us the
working configuration. Or if you have any suggestion to share I will be
very grateful. The routers are: MX480-1 and MX480-2 in one site and
OSR-1 and OSR-2 on another site.
Thank you in advance.
Br,
Edmar
