If i understand it correctly, one can use regular extended communities even for the redirect. The IPv6 address-specific extended community is here just an alternative to type 0x80 / 0x81 / 0x82 extended community. It just have to match the route-target community used for the VRF. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) "To err is human -- to blame it on a computer is even more so."
