vlan
Sets the vc type to 0x04 (Ethernet tagged mode).
Enabling the Revert Timer
The
revert-timer
command, in VPLS Configuration mode, specifies the amount of time (in
seconds) that the LSP must wait before reverting the traffic back to a primary path. If during this
period the primary path experiences any connectivity problem, the timer will be restarted.
The default value is 60 seconds.
Command Syntax
device-name
(config-vpls
ID
)#
revert-timer <0-600>
device-name
(config-vpls
ID
)#
no revert-timer
Argument Description
0-600
Length of the revert timer, in seconds.
Configuring Dynamic Spoke Service Distribution Paths (SDP) for
VPLS
The
spoke-sdp
command, in VPLS configuration mode, defines a VLL (Pseudowire) for the
specified VPLS instance. The spoke is a dynamic one, because LDP protocol is used to negotiate
labels.
A single
spoke SDP
can be defined per VPN. The
backup spoke SDP
is an option.
When a hardware failure occurs on the selected uplink port (link loss), the MPLS Hardware & H-
VPLS driver will switch to the backup spoke SDP, if such is defined.
The
no
form of this command removes the previously defined dynamic spoke SDP (or backup, if
specified).
NOTE
On the switch, all primary spoke SDPs should point at one and the same LDP peer.
All secondary spoke SDPs should also point at the one and the same LDP peer.
Note that the LDP peer pointed at by the primary spoke SDPs and the LDP peer
pointed at by the secondary spoke SDPs must never coincide.

Argument Description
backup
(Optional). Specifies that the spoke SDP will be used as a backup spoke
SDP.
UU/SS/PP
Represents the outgoing interface (physical port) for the selected
Pseudowire. One of the Uplink ports must assume the role of the
outgoing interface.
