[c-nsp] eBGP Peer with non-bgp transit router in the middle

2007-08-28 Thread William Jackson
Hi all A recommendation on preferred method of achieving the following scenario: [AS Y BGP Router]---[AS Z transit router][AS Z BGP router] AS Y router config Neighbor BGP-Z-loopback as Z Neighbor BGP-Z-loopback ebgp-multihop 10 Ip route x.x.x.x.
