Options
The following options are available:
PE-ID — IP address that identifies the PE router.
•
interface-ip — Interface IP address for the PE router. This is used for MAC resolution.
•
–
–
–
vlan — A VLAN tag can optionally be provided for each interface IP.
•
Two interfaces cannot be defined with the same IP address, even if they have different VLAN tags. If
such a configuration is attempted, it will simply update the VLAN tag information for the existing PE
interface.
How to Add a PE Router
Each PE router that has managed VPNs behind it must be defined using the following CLI command.
From the SCE(config if)# prompt, type MPLS VPN PE-ID pe-id interface-ip-address interface-ip
Step 1
[vlan vlan] and press Enter.
Defines the PE router with with one interface IP address and optional VLAN tag. May also be used to
add an additional interface IP address to an existing PE router.

About Removing PE Routers
Use these commands to remove one or all defined PE routers.
Please note the following:
You cannot remove a PE if it retains any MPLS mappings. You must logout the VPN and remove all
•
mappings before removing the router it uses. (You must use the SM CLU to remove VPN mappings.)
Removing the last interface of a PE router removes the router as well. Therefore, you must logout
•
the relevant VPN to remove the last interface.
Likewise, all VPNs must be logged out before using the no PE-Database command below, since it
•
removes all PE routers.
How to Remove a Specified PE Router
Step 1
From the SCE(config if)# prompt, type no MPLS VPN PE-ID pe-id and press Enter.
Removes the specified PE router.
OL-7827-12
At least one interface IP address must be defined per PE router.
Multiple interface IP addresses may be defined for one PE router.
In the case where the PE router has multiple IP interfaces sharing the same MAC address, it is
sufficient to configure just one of the PE interfaces
