The remote-mac-address may be any unicast, broadcast of multicast address. However, a
broadcast or multicast remote-mac-address is only allowed in the static-arp command on Ethernet
unnumbered interfaces when the unnumbered-mpls-tp keyword has been configured. This also
allows the interface to accept packets on a broadcast or any multicast MAC address. Note that if a
packet is received with a unicast destination MAC address, then it will be checked against the
configured <local-mac-address> for the interface, and dropped if it does not match. When an
interface is of type unnumbered-mpls-tp, only MPLS-TP LSPs are allowed on that interface;
other protocols are blocked from using the interface.
An unnumbered MPLS-TP interface is assumed to be point-to-point, and therefore users must
ensure that the associated link is not broadcast or multicast in nature if a multicast or broadcast
remote MAC address is configured.
The following is a summary of the constraints of an unnumbered MPLS-TP interface:
• It is unnumbered and may borrow/use the system interface address
• It prevents explicit configuration of a borrowed address
• It prevents IP address configuration
• It prevents all protocols except MPLS
• It prevents Deletion if an MPLS-TP LSP is bound to the Interface
• It is allowed only in network chassis mode D
MPLS-TP is only supported over Ethernet ports. The system will block the association of an
MPLS-TP LSP to an interface whose port is non-Ethernet.
LER Configuration for MPLS-TP
LSP and Path Configuration
MPLS-TP tunnels are configured using the mpls-tp LSP type at an LER under the LSP
configuration, using the following CLI tree:
config
router
mpls
lsp <xyz> [bypass-only|mpls-tp <src-tunnel-num>]
to node-id {<a.b.c.d> | <1.. .4,294,967,295>}
dest-global-id <global-id>
dest-tunnel-number <tunnel-num>
