ipv4-address: Soft-resets the connection with an IPv4 BGP peer.

ipv6-address: Soft-resets the connection with an IPv6 BGP peer.

all: Soft-resets all IPv6 BGP connections.

external: Soft-resets EBGP connections.

group ipv6-group-name: Soft-resets connections with a peer group. The name of 
the peer group is a string of 1 to 47 characters.

internal: Soft-resets IBGP connections.

export: Performs soft reset in outbound direction.

import: Performs soft reset in inbound direction.

Use the refresh bgp ipv6 command to soft reset specified IPv4/IPv6 BGP 
connections. With this feature, you can refresh the IPv4/IPv6 BGP routing table 
and apply a new available policy without tearing down IPv4/IPv6 BGP connections.

To perform IPv4/IPv6 BGP soft reset, all routers in the network should support 
route-refresh. If a router not supporting route refresh exists in the network, you 
need to use the peer keep-all-routes command on the local router to save all 
route updates before performing soft reset.
