peer backup
This command is used to create a backup peer for PW redundancy of H-VPLS.
peer backup
IP-ADDRESS
[
VC-ID
]
Parameters
Example
This example shows how to delete a peer from a VPLS
with the IP address if 2.2.2.2
and VC ID of 100.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#vpls vpls100
DXS-3600-32S(config-vpls)#no peer 2.2.2.2 100
DXS-3600-32S(config-vpls)#
Example
This example shows how to delete all peers from a VPLS with the IP address of
2.2.2.2.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#vpls vpls100
DXS-3600-32S(config-vpls)#no peer 2.2.2.2
DXS-3600-32S(config-vpls)#
IP-ADDRESS
Specifies the LSR ID that is used to identify the PE which the peer belongs to.
VC-ID
(Optional) Specifies the pseudowire ID. This ID must be between 1 and 4294967295.
It is used with the
IP-ADDRESS
to uniquely identify a peer for a VPLS. If no ID is
specified, the pseudowire ID will be the same as the VPLS ID of this VPLS.
Default
The VC-ID is set by the VPLS ID of this VPLS
Command Mode
VPLS Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
This command is used to create a backup peer for PW redundancy of an H-VPLS in
the VPLS configuration mode. To reach PW redundancy in an H-VPLS, the device
will act as an MTU-s and there should be one primary pseudowire and one backup
pseudowire configured.
In a normal situation the primary pseudowire is link up and the backup pseudowire is
link standby. The packet forwarding between the MTU-s and PE will work on the
primary pseudowire.When the LDP hello procedure fails the primary pseudowire link
is down, the backup pseudowire will be changed to link up to take over the packet
forwarding between the MTU-s and the PE. After the primary pseudowire is
recovered to link up, the backup pseudowire will be toggled back to link standby and
the packet forwarding between the MTU-s and the PE will be back to the primary
pseudowire again.
When the backup pseudowire is changed from link standby to link up, the MAC
withdraw message with a NULL-MAC list will be sent from the MTU-s to the PE via
the backup pseudowire to clear old MAC addresses. When the primary pseudowire
is recovered to link up and the backup pseudowire is changed from link up to link
standby, the MAC withdraw message with a NULL-MAC list will be sent from the
MTU-s to the PE via the primary pseudowire to clear old MAC addresses.
