Hi Hemant,
Thanks!!
(1) Yes, I have to run BGP on this tunnel. If for this I need to set gr-0/0/0 or st0 with family inet IP. Is this the same IP as the BGP router-id? For BGP over GRE over IPsec, both gr-0/0/0 and st0 need this family inet IP or just gr-0/0/0? If both need, could we use same ip?
(2) For my ISG to SRX swap, former ISG2000 configuration, we have loopback.2 public ip x.x.x.x/32 used for BGP, which is same as bgp router-id. While loopback.1 is tunnel endpoint x.x.x.x/32.
So if I configure family inet IP for gr-0/0/0 or st0 interface, do I still need to configure a loopback unit 2 family inet IP as above? If yes, same IP is ok?
