[c-nsp] Does IOS-XR support exchange of IPv6 prefixes over an IPv4 BGP peering

[Tassos Chatzithomaoglou]

Can someone verify whether it's possible to exchange IPv6 prefixes over 
an IPv4 BGP peering in IOS-XR?



According to an old doc in 
http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.3/conversion/reference/guide/cn33main.html#wp1028960

*Note *A given address family is only supported with a neighbor whose 
address is from that address family. For instance, IPv4 neighbors 
support IPv4 unicast and multicast address families, and IPv6 neighbors 
support IPv6 unicast and multicast address families. However, you cannot 
exchange IPv6 routing information with an IPv4 neighbor and vice versa.
