Default Level
2: Monitor level
Parameters
all: Soft-resets all BGP connections.
ip-address: IP address of an IPv4 MBGP peer.
group-name: Peer group name, a string of 1 to 47 characters.
external: Soft-resets EBGP connections.
internal: Soft-resets IBGP connections.
export: Outbound soft reset.
import: Inbound soft reset.
Description
Use the refresh bgp ipv4 multicast command to perform soft reset on specified IPv4 MBGP
connections. This method can also refresh the MBGP routing table and apply a new route policy
seamlessly.
To perform BGP soft reset, all routers in the network must support route-refresh. If there is a router not
supporting the route-refresh function, you need to configure the peer keep-all-routes command to
save all the routing information of the peer before BGP soft reset.
Examples
# Soft-reset all the IPv4 MBGP connections.
