refresh bgp ipv4 unicast Use refresh bgp ipv4 unicast to manually soft-reset BGP sessions for the IPv4 unicast address family. Syntax refresh bgp { ip-address | all | external | group group-name | internal } { export | import } ipv4 [ unicast ] [ vpn-instance vpn-instance-name ] Views User view Predefined user roles network-admin Parameters ip-address: Soft-resets the BGP session to the specified peer. The ip-address argument refers to the IP address of a peer. all: Soft-resets all BGP sessions. external: Soft-resets all EBGP sessions. group group-name: Soft-resets the BGP sessions to the peers of the specified peer group. The group-name argument refers to the name of a peer group, a case-sensitive string of 1 to 47 characters. internal: Soft-resets all IBGP sessions. export: Performs outbound soft-reset (filters routes advertised to the specified peer or peer group by using the new configuration). import: Performs inbound soft-reset (filters routes received from the specified peer or peer group by using the new configuration). vpn-instance vpn-instance-name: Specifies an MPLS L3VPN by its name, a case-sensitive string of 1 to 31 characters. If no VPN is specified, this command performs manual soft-reset on BGP sessions for the public network IPv4 unicast address family. Usage guidelines After the route selection policy is modified, execute this command with the export keyword to enable the local router to filter routing information based on the new policy and send the matching routes to the BGP peer. If you execute this command with the import keyword, you enable the local router to advertise a route-refresh message to the peer and the peer resends its routing information to the router. After receiving the routing information, the router filters the routing information by using the new policy. This command requires that both the local router and the peer support route refresh. If the peer keep-all-routes command is configured, the refresh bgp ipv4 unicast import command does not take effect. The command with the unicast keyword has the same effect as that without the unicast keyword.

refresh bgp ipv4 unicast
Use
refresh bgp ipv4 unicast
to manually soft-reset BGP sessions for the IPv4 unicast address family.
Syntax
refresh bgp
{
ip-address
|
all
|
external
|
group
group-name
|
internal
} {
export
|
import
}
ipv4
[

Views

Predefined user roles
network-admin
Parameters
ip-address
: Soft-resets the BGP session to the specified peer. The
ip-address
argument refers to the IP
address of a peer.
all
: Soft-resets all BGP sessions.
external
: Soft-resets all EBGP sessions.
group
group-name
: Soft-resets the BGP sessions to the peers of the specified peer group. The
group-name
argument refers to the name of a peer group, a case-sensitive string of 1 to 47 characters.
internal
: Soft-resets all IBGP sessions.
export
: Performs outbound soft-reset (filters routes advertised to the specified peer or peer group by using
the new configuration).
import
: Performs inbound soft-reset (filters routes received from the specified peer or peer group by using
the new configuration).
vpn-instance
vpn-instance-name
: Specifies an MPLS L3VPN by its name, a case-sensitive string of 1 to 31
characters. If no VPN is specified, this command performs manual soft-reset on BGP sessions for the
public network IPv4 unicast address family.
Usage guidelines
After the route selection policy is modified, execute this command with the
export
keyword to enable the
local router to filter routing information based on the new policy and send the matching routes to the BGP
peer. If you execute this command with the
import
keyword, you enable the local router to advertise a
route-refresh message to the peer and the peer resends its routing information to the router. After
receiving the routing information, the router filters the routing information by using the new policy.
This command requires that both the local router and the peer support route refresh.
If the
peer keep-all-routes
command is configured, the
refresh bgp ipv4 unicast import
command does
not take effect.
The command with the
unicast
keyword has the same effect as that without the
unicast
keyword.
Examples
# Manually soft-reset all BGP sessions for the IPv4 unicast address family.
