Configuring EBGP between MCE and VPN site
To use EBGP for exchanging routing information between an MCE and VPN sites, you must configure a
BGP peer for each VPN instance on the MCE, and redistribute the IGP routes of each VPN instance on
the VPN sites.
If EBGP is used for route exchange, you also can configure filtering policies to filter the received routes
and the routes to be advertised.
