Q:
How to configure default route to the site connected with opposite PE on local PE?
Handling Process
On local PE configure as follows and add default route to VPN routing table:
ip route-static vpn-instance vpna 0.0.0.0 0.0.0.0 LoopBack 0 x.x.x.x
loopback 0 is for local PE setting up MBGP, x.x.x.x is the address with which opposite PE sets up MBGP loopback.
