Default EoMPLS Configuration
By default, EoMPLS is not configured.
The mpls ldp router-id command is disabled. No virtual connections are configured.
EoMPLS Configuration Guidelines
When you configure EoMPLS, you must follow these guidelines:
•
Before enabling EoMPLS, you must enable dynamic MPLS labeling by using the mpls ip interface
configuration command on all paths between the imposition and disposition LERs. MPLS is
globally enabled by default.
•
For VLAN-based EoMPLS, you must configure VLANs on the switch.
•
EoMPLS operation between two provider-edge routers requires an LDP session between the routers.
The IP address used by each router as its LDP router ID must be reachable through IP by the other.
Use the optional mpls ldp router-id global configuration command to control the selection of the
LDP router ID by specifying the interface whose IP address should be used.
–
If the specified interface is up and has an IP address, you can use the command without the
optional force keyword. When the router ID is selected, that IP address is selected as the router
ID.
–
If the specified interface is not up or does not have an IP address, use the force keyword with
the command to ensure that the IP address of the specified interface is used when that interface
is brought up.
•
Both provider-edge routers require a loopback address that you can use to create a virtual connection
between the routers. When you use OSPF as the interior gateway protocol, you must configure all
loopback addresses on provider-edge routers with 32-bit masks to ensure proper operation of MPLS
forwarding between the provider-edge routers.
•
Do not configure EoMPLS on an interface configured for VLAN mapping.
•
You can set the maximum transmission unit (MTU) value on an SVI.
Configuring EoMPLS
You configure VLAN-based EoMPLS on a VLAN interface. When VLAN-based EoMPLS is enabled,
the switch associates the tunnel and virtual-connection labels based on the VLAN ID. You use the same
commands to enable port-based EoMPLS.
