I'm having a problem with my BGP route advertised from R5 to R6. R5 (AS5) and
R6 (AS6) are peering using their link-local addresses:
R5(vlan567)-------------------------------(e0/0)R6
R5(L0) - 2001::5:0/112
R5 has a route-map advertising it's global address (2001::5) as the next-hop
for network 2001::5:0/112. R6 has the correct next hop in it's bgp table, but
has a link-local address of FE80:: in it's routing table as the next hop. The
result is:
r6#ping 2001::5:1
3d04h: IPv6: SAS picked source 2001::6 for 2001::5:1 (Ethernet0/0)
3d04h: IPv6: nexthop FE80::,
3d04h: IPV6: source 2001::6 (local)
3d04h: dest 2001::5:1 (Ethernet0/0)

3d04h: IPv6: Resolving next hop FE80:: on interface Ethernet0/0.
3d04h: IPV6: source 2001::6 (local)
Can someone point out what I'm doing wrong.
