Inter-AS MPLS Option 2 - VPNv4 exchange
Just going over Brian's ATC video for this, I am confused about one part of it.
when we are peering between the Service providers using ebgp vpnv4...
say ... R1 ( AS1) ------ XR1 (AS2)
the IOS router ( R1) automatically creates the command ( mpls bgp forwarding ) under the interface that peers to XR1, it also creates a /32 host route for XR1.
Now on XR1, we need to create the /32 static host route to R1, but is there also any additional commands IOS XR does to send labelled traffic over that link ? similar to the 'mpls bgp forwarding' that the IOS router did.
