IP Router Configuration Command Reference
128 Router Configuration Guide
generate-icmp
Syntax [no] generate-icmp
Context config>router>static-route-entry>black-hole
Description This optional command causes the ICMP unreachable messages to be sent when received packets
match the associated static route. By default, the ICMP unreachable messages for those types of static
routes are not generated.
This command can only be associated with a static route that has a blackhole next-hop
The no form of this command removes the black-hole nexthop from the static route configuration.
Default no generate-icmp
forwarding-class
Syntax [no] forwarding-class {be | l2 | af | l1 | h2 | ef | h1 | nc}
Context config>router>static-route-entry>next-hop
config>router>static-route-entry>indirect
config>router>static-route-entry>next-hop
Description This command specifies the enqueuing forwarding class that should be associated with traffic
matching the associate static route. If this parameter is not specified, the packet will use the
forwarding-class association based on default classification or other QoS Policy associations.
Default no forwarding-class
Parameters be | l2 | af | l1 | h2 | ef | h1 | nc — specifies the forwarding class
Values be | l2 | af | l1 | h2 | ef | h1 | nc
ldp-sync
Syntax [no] ldp-sync
Context config>router>static-route-entry>next-hop
config>router>static-route-entry>indirect
config>router>static-route-entry>next-hop
Description This command extends the LDP synchronization feature to a static route. When an interface comes
back up, it is possible that a preferred static route using the interface as next-hop for a given prefix is
enabled before the LDP adjacency to the peer LSR comes up on this interface. In this case, traffic on
an SDP that uses the static route for the far-end address would be black-holed until the LDP session
comes up and the FECs exchanged.
