People,
We are trying to close a GRE tunnel between juniper and Cisco routers
without success.
We have tried a lot of MTU configurations but the traffic is suffering
a lot ... sometimes slow, sometimes do not open some pages.
Have you ever configured something like this before ?
Any tip ou configuration related to best practices ?
Thanks a lot,
Giuliano
