Field DescriptionField Name
Indicates the status of a BGP route:
• Accepted—The specified BGP route is imported by the default BGP policy.
• Import—The route is imported into a Layer 3 VPN routing instance.
• Import-Protect—A remote instance egress that is protected.
• Multipath—A BGP multipath active route.
• MultipathContrib—The route is not active but contributes to the BGP multipath.
• Protect—An egress route that is protected.
• Stale—A route that is marked stale due to graceful restart.
route status
When multipoint LDP with multicast-only fast reroute (MoFRR) is configured, the primary upstream
path. MoFRR transmits a multicast join message from a receiver toward a source on a primary path,
while also transmitting a secondary multicast join message from the receiver toward the source on
a backup path.
Primary Upstream
When multipoint LDP with MoFRR is configured, the reverse-path forwarding (RPF) next-hop
information. Data packets are received from both the primary path and the secondary paths. The
redundant packets are discarded at topology merge points due to the RPF checks.
RPF Nexthops
Multiple MPLS labels are used to control MoFRR stream selection. Each label represents a separate
route, but each references the same interface list check. Only the primary label is forwarded while all
others are dropped. Multiple interfaces can receive packets using the same label.
Label
Value used to distinguish MoFRR primary and backup routes. A lower weight value is preferred. Among
routes with the same weight value, load balancing is possible.

Community path attribute for the route. See the Output Field table in the show route detail command
for all possible values for this field.

Maximum transmission unit (MTU) information.mtu
First label in a block of labels and label block size. A remote PE routing device uses this first label
when sending traffic toward the advertising PE routing device.
