neighbor next-hop-self

Description

Configures the router as the next hop for a BGP-speaking neighbor or peer group, and enables BGP to send itself as the next hop for advertised routes.

The no form of this command resets the peer nexthop-self status to default. The next hop will be generated based on the IP.

Command context

config-bgp-ipv4-uc

config-bgp-ipv6-uc

Parameters

<IP-ADDR>

Specifies the neighbor's IP address in IPv4 format (x.x.x.x), where x is a decimal number from 0 to 255, or IPv6 format (xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx), where x is a hexadecimal number from 0 to F.

<PEER-GROUP-NAME>

Specifies a peer group.

all

Applies the configuration to all route-reflector clients.

Authority

• This command is useful in non-meshed networks where BGP neighbors may not have direct access to all other neighbors on the same IP subnet.
