egress-engineering peer-set

Function

The egress-engineering peer-set command creates a BGP peer set.

The undo egress-engineering peer-set command deletes a BGP peer set.

By default, no BGP peer set is created.

Usage Guidelines

Usage Scenario

Border Gateway Protocol (BGP) is a dynamic routing protocol used between ASs. BGP egress peer engineering (EPE) is an extension of BGP for segment routing and is used to implement source routing between ASs.

BGP EPE can allocate BGP peer SIDs to inter-AS paths, and the peer SIDs can then be advertised to a network controller through extended BGP-LS functions. The controller orchestrates IGP SIDs and BGP peer SIDs to implement inter-AS forwarding over the optimal path.

Besides peer nodes and peer adjacencies, there are also peer sets. You can manually plan a group of peers as a peer set and allocate a SID to the group. This SID can correspond to multiple outbound interfaces.

Precautions

A peer set cannot be deleted if it is referenced by a public IPv4 peer.

Example

# Create a BGP peer set.

<HUAWEI> system-view
[~HUAWEI] bgp 100
[*HUAWEI-bgp] egress-engineering peer-set group1

# Configure a device to search its routing table when detecting an interface down event during traffic forwarding based on BGP-EPE label.

<HUAWEI> system-view
[~HUAWEI] bgp 100
[*HUAWEI-bgp] egress-engineering peer-set group1 label 32
[*HUAWEI-bgp] egress-engineering peer-set group1 link-down label-pop

# Associate BGP-EPE labels with SBFD packets.

<HUAWEI> system-view
