Notes
The VPN target is a label filtering policy used by VPLS
in BGP signaling mode. Two VPN-target formats exist:
AS:nn and IP:nn. AS represents the autonomous system
number; nn is the user-defined figure; IP represents a
local IP address.
Ensure the association between the local VPN target
attribute and the remote VPN target attribute:
• The local export-extcommunity attribute and the
remote import-extcommunity attribute are consistent.
• The local import-extcommunity attribute and the
remote export-extcommunity attribute are consistent.
The traffic can flow in two-way only when the preceding
two requirements are satisfied.
The traffic can flow only in one-way if one of the two
requirements is met.
In general, the four values are configured consistent for
convenience.
You must specify an RD before you configure the VPN
target.
RDs on a same router cannot be set to the same value.
Site ID is used to specify a VSI site, ranging from
0-65534. A site ID must be unique in a VPLS.
The local site ID must not be larger than the sum of
range and default-offset of the peer. The local site ID
must be larger than default-offset of the peer.
range shows the number of sites in a VSI, with the
maximum range of 1-65534. default-offset is 0 or 1.
A tunnel policy is configured in the system view. VPLS
specifies the policy to be used. Besides the VPLS tunnel
policy you can specify a policy for a certain peer. By
default, the LSP tunnel is chosen. You need to complete
basic VPLS configuration before you configure a tunnel
policy.
In LDP mode, you need to configure a VSI ID first. In
BGP mode, you need to specify an RD first.
