I have configured following senario
I have configured the IBGP between PE1 and PE2 with physical interface IP address.
I can see the BGP session is UP between PE1 and PE2.
I have configured (activate) MP-IBGP between PE1 and PE2.
And i received the following message on the PE1 router.
%BGP-4-vpnv4NH_IF:next-hop 10.10.10.1 may not be reachable from neighbour 10.10.30.2 - not a loopback.
Can anyone please explain me what is this mean?
