This command configures EBGP peer routes to not contain the specified neighbor‘s AS.
| ip-address | Specifies a BGP peer as a valid IPv4 address in dotted-quad format or as a valid IPv6 address in colon-separated format. |
Some routers are capable of propagating routes without appending their own autonomous system number to the AS Path. By default, the S- and 7100-Series Router will drop such routes. The neighbor ignore-leading-as command allows the S- and 7100-Series Router to keep these routes for EBGP peers. This capability may be needed if the peer has policy that prevents it from pre-pending its own AS number to the AS path.
The no neighbor ignore-leading-as command resets this command to the default value of disabled.
None.
BGP Router Configuration.
