Configures the MPLS LSR ID for the switch.
| ipaddress | Specifies an IP address to identify the MPLS LSR for the switch. The MPLS LSR-ID should be configured to the same IP address as the OSPF Router ID. |
No LSR ID is configured by default.
LDP, RSVP-TE, and L2 VPNs all use the LSR ID. It is normally set to the OSPF Router ID.
The LSR ID must be configured before MPLS can be enabled. The LSR ID cannot be changed while MPLS is enabled. It is highly recommended that an IP address be configured on a OSPF enabled loopback VLAN that matches the configured LSR ID and OSPF ID. If an LSR ID loopback IP address is configured, OSPF automatically advertises the LSR ID as a routable destination for setting up LSPs. The LSR ID remains active if an interface goes down if the LSR-ID is configured as an IP address on a loopback VLAN, as recommended. This significantly enhances network stability and operation of an MPLS network.
The following command configures the LSR ID to 192.168.50.5:
configure mpls lsr-id 192.168.50.5
This command was first available in ExtremeXOS 11.6.
This command is available only on the platforms that support MPLS as described in the Switch Engine v33.1.1 Licensing Guide document.
