I receive ::/0 from our transit peer, and announce it to a reflector. Apart from next hep set to self, nothing else is changed.
On the reflector, I am not receiving prefix ::/0, but ::/8 instead, and pointing at next hop of peering node facing transit router.
::/8 is not even received on the peering node facing transit.
Config wise, I peer on IPv6 subnet facing transit, then 6PE towards the backbone, therefore sending labels under address family ipv6.
I am unable to replicate this in Lab environment.
sh bgp ipv6 unicast ::/0
BGP routing table entry for ::/8, version 76796277
Paths: (3 available, best #2, table default)
Has anyone seen similar issue ?
After more troubleshooting, I am suspecting a bug on 12.2(33)SRE5.
I cannot see how else a prefix sent as ::/0 is received as ::/8. Sending node is XR based which filter ::/8 natively.
