Weighted Load Balancing Static Route Packets Over Mpls Lsp - Alcatel-Lucent 7450 Configuration Manual

Weighted Load Balancing Static Route Packets over MPLS LSP

Feature Configuration
The user enables the resolution of a static route to a one or more MPLS P2P LSPs in TTM using
the following new static route configuration command:
config>router>static-route-entry {ip-prefix/prefix-length} [mcast] indirect {ip-address} tunnel-next-hop
— resolution {any|disabled|filter}
— resolution-filter
— [no] disallow-igp
— exit
exit
The user can either provide a list of LSP names or let the automatic selection of the LSP tunnel
next-hops from the TTM by configuring resolution to the any value. These are mutually
exclusive. A maximum of 128 LSP names can be entered within a static route prefix configuration.
Note that a P2P auto-lsp instantiated via an LSP template can be selected in TTM when resolution
is set to any. It is however not recommended to configure an auto-lsp name explicitly under the
rsvp-te node as the auto-generated name can change if the node reboots which will black-hole
traffic of the static route.
The above command is covered in much more details in
page 51
given static route of a prefix can only be resolved to a set of tunnel next-hops of the same type
though for each indirect next-hop.
The existing static-route command is still supported with all other options, including the indirect
one which can be used to resolve the indirect next-hops in RTM. The new command is an add-on
to configure the resolution to tunnel next-hops in TTM. As such, the user must first configure the
prefix with the existing command and the indirect option and then enter the new command with
the indirect option and with the new static-route-entry command. Here is an example:
/configure router static-route 5.5.5.5/32 indirect 1.0.0.2
/configure router static-route-entry 5.5.5.5/32 indirect 1.0.0.2
