mpls traffic-eng mesh-group
To configure a mesh group in an Interior Gateway Protocol (IGP) to allow Multiprotocol Label
Switching (MPLS) traffic engineering (TE) label switch routers (LSRs) that belong to the same mesh
group to signal tunnels to the local router, use the mpls traffic-eng mesh-group command in router
configuration mode. To disable signaling of tunnels from LSRs in the same mesh group to the local
router, use the no form of this command.

Syntax Description
Command Default No tunnels are signaled for routers in the same mesh group.
Command Modes Router configuration (config-router)#
Command History
Usage Guidelines Use this command to configure a mesh group in an IGP
. This allows the MPLS TE LSRs that belong to
the specified mesh group to signal tunnels to the local router. The IGP floods mesh group configuration
to all routers belonging to the same mesh group. An autotemplate determines how a router participates
in an autotunnel. A router can participate in a mesh group through two-way tunnels or one-way tunnels.
Open Shortest Path First (OSPF) is the o
nly IGP supported for the MPLS Traffic
Engineering—AutoTunnel Mesh Groups feature.
Examples The following example shows how to configure OSPF to allow LSRs that belong to the same mesh group
(m
esh group 10) to signal tunnels to the local router:
Router(config)# router ospf 100
Router(config-router)# mpls traffic-eng mesh-group 10 loopback 0
area 100
mesh-group-id Number that identifies a specific mesh group.
type Type of interface.
number Interface number.
area ar
ea-id Specifies an IGP area.
