The unicast-route recursive-lookup tunnel command allows non-labeled private BGP routes to recurse to LSPs.
The undo unicast-route recursive-lookup tunnel command restores the default configuration.
By default, non-labeled private BGP routes cannot recurse to LSPs.
| Parameter | Description | Value |
|---|---|---|
| tunnel-selector tunnel-selector-name |
Specifies the name of a tunnel policy selector. |
The value is a string of 1 to 40 case-sensitive characters, spaces not supported. The character string can contain spaces if it is enclosed with double quotation marks (") when being entered. |
Usage Scenario
By default, non-labeled private BGP routes can recurse to outbound interfaces and next hops, but not to LSPs. To allow non-labeled private BGP routes to preferentially recurse to LSPs, run the unicast-route recursive-lookup tunnel command. If no LSPs are available after the command is run, non-labeled private BGP routes recurse to outbound interfaces and next hops.If tunnel-selector is specified in the command, non-labeled private BGP routes recurse to the LSPs that match the specified tunnel policy selector.
Precautions
If the unicast-route recursive-lookup tunnel command is run more than once, the latest configuration overrides the previous one.
The SRv6 TE Policy or SRv6 TE Policy Group of tunnel is not supported in a tunnel selector specified in the command.<HUAWEI> system-view [~HUAWEI] ip vpn-instance vpna [*HUAWEI-vpn-instance-vpna] ipv4-family [*HUAWEI-vpn-instance-vpna-af-ipv4] route-distinguisher 1:1 [*HUAWEI-vpn-instance-vpna-af-ipv4] quit [*HUAWEI-vpn-instance-vpna] quit [*HUAWEI] tunnel-selector test permit node 10 [*HUAWEI-tunnel-selector] quit [*HUAWEI] bgp 100 [*HUAWEI-bgp] ipv4-family vpn-instance vpna [*HUAWEI-bgp-vpna] unicast-route recursive-lookup tunnel tunnel-selector test
