Hierarchy Level


Configure the router to perform custom route resolution on protocol next hops of routes in a certain routing table. The protocol next hop is used to determine the forwarding next hop.

For example, you might want to direct inet.2 route resolution to use topology routing tables :red.inet.0 and :blue.inet.0 for protocol next-hop IP address lookups. Or you might want to direct bgp.l3vpn.0 to use the information in inet.0 to resolve routes, thus overriding the default behavior, which is to use inet.3.

You can specify up to two routing tables in the resolution-ribs statement. The route resolution scheme first checks the first-listed routing table for the protocol next-hop address. If the address is found, it uses this entry. If it is not found, the resolution scheme checks the second-listed routing table. Hence, only one routing table is used for each protocol next-hop address. For example, if you configure resolution rib bgp.l3vpn.0 resolution-ribs [inet.0 inet.3], inet.0 is checked first and then inet.3 is checked.


Customizing route resolution might cause the routing protocol process (rpd) to consume more memory resources than it ordinarily would. When you customize route resolution, we recommend that you check the memory resources by running the show system processes and the show task memory commands. For more information, see Routing Protocol Process Overview for EX Series Switches.

The remaining statements are explained separately. See CLI Explorer.


inet-import [ policy-names ]

(Optional) Import policy for IPv4 family resolution tree.

inet-resolution-ribs [ routing-table-names

(Optional) Specify routing tables to use for IPv4 family protocol-next-hop resolution.

inet6-import [ policy-names ]

(Optional) Import policy for IPv6 family resolution tree.

inet6-resolution-ribs [ routing-table-names ]

(Optional) Specify routing tables to use for IPv6 family protocol-next-hop resolution.

Enabling the inet6-resolution-ribs option causes the static LSP route resolution to happen over the more preferred resolving route (lowest protocol preference) among the longest-matching-prefix routes in both the inet6.0 and inet6.3 routing tables.

iso-import [ policy-names ]

(Optional) Import policy for ISO family resolution tree.

iso-resolution-ribs [ routing-table-names ]

(Optional) Specify routing tables to use for ISO family protocol-next-hop resolution.

resolution-family resolution-family

(Optional) Specify a family of resolution tree.

preserve-nexthop-hierarchy Preserve nexthop hierarchy when installing nexthop to forwarding plane.
