if-match ipv6 next-hop prefix-list (Tunnel-selector view)

Function

The if-match ipv6 next-hop prefix-list command configures a rule for matching routes based on the IPv6 next hop for a tunnel selector.

The undo if-match ipv6 next-hop prefix-list command deletes the setting.

By default, IPv6 route filtering based on the next hop is not configured.

Format

if-match ipv6 next-hop prefix-list ipv6-prefix-name

Usage Guidelines

Usage Scenario

The if-match ipv6 next-hop prefix-list command can be run in the tunnel-selector view in the following scenarios:

The ASBR in inter-AS VPN Option B networking needs to apply a tunnel policy to VPNv6 routes. For example, the ASBR has the VPNv6 routes recurse to MPLS TE tunnels.
A PE in inter-AS VPN Option C networking needs to apply a tunnel policy to labeled BGP-IPv6 routes. For example, the PE has the labeled BGP-IPv6 routes recurse to MPLS TE tunnels.
The if-match ip next-hop command is used to apply a tunnel policy to the VPNv6 or labeled BGP-IPv6 routes with a specified next hop, not all VPNv6 or labeled BGP-IPv6 routes.

Follow-up Procedure

Run the apply tunnel-policy command in the tunnel-selector view to apply a tunnel policy to the matched routes.

Example

# Configure IPv6 route filtering based on the next hop.

<HUAWEI> system-view
[~HUAWEI] ip ipv6-prefix ipv6prefix permit ::0 32
[*HUAWEI] tunnel-selector abc permit node 10
[*HUAWEI-tunnel-selector] if-match ipv6 next-hop prefix-list ipv6prefix
