This command exchanges IPv4 or IPv6 address family information with an IPv4, IPv6, and L2VPN
neighbor. IPv4 unicast Address family is enabled by default. To activate IPv6 address family for IPv6
neighbor, use the activate command. To deactivate IPv4 address family for IPv6 neighbor, use the no
activate command.

Parameters
● both path count — Enter the number of paths to advertise to the peer, from 2 to 64.
● receive — Receive multiple paths from the peer.

new path reduces convergence times. The no version of this command disables the multiple path
advertisements for the same destination.

Example (IPv6)
OS10(conf-router-bgpv6-af)# add-path both 64
Example
