next-hop-recursion

Enables BGP recursive next-hop lookups.

Syntax

next-hop-recursion

no next-hop-recursion

Command Default

This feature is disabled.

Modes

BGP address-family IPv4 unicast configuration mode

BGP address-family IPv6 unicast configuration mode

Usage Guidelines

Use the no form of this command to restore the default.

If the BGP next hop is not the immediate next hop, a recursive route lookup in the IP routing information base (RIB) is needed. With recursion, a second routing lookup is required to resolve the exit path for destination traffic. Use this command to enable recursive next-hop lookups.

Examples

This example enables recursive next-hop lookups for BGP4.

device# configure terminal
device(config)# address-family ipv4 unicast
device(config-bgp-ipv4u)# next-hop-recursion

This example enables recursive next-hop lookups for BGP4+.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# next-hop-recursion
