abdosi 15a39ac806 Fix the Loopback0 IPv6 address of LC's in chassis not reachable from (#16026)
What I did:
Fix the Loopback0 IPv6 address of LC's in chassis not reachable from peer devices.

Why I did:
For Ipv6 Loopback0 address we only advertise /64 subnet to the peer devices. However, in case of chassis each LC will have it own /128 address of that /64 subnet . Since this /128 address does not get advertised peer devices can-not ping/reach the LC's loopback0.

How I fix:
Advertise /128 Loopback0 Ipv6 address only between i-BGP peers. This way even though /64 is advertised to e-BGP peer devices when packet reaches any of LC's it can reach the appropriate LC's.

How I verify:
Manual verification
UT added for same.
