Configuring BIERv6

Configuring BIERv6 involves configuring basic BIERv6 functions and enabling IS-ISv6 BIERv6. You also need to configure inter-AS static traversal if you deploy the BIERv6 network across ASs. In cases where an AS contains nodes that do not support BIERv6 forwarding, intra-AS automatic traversal is automatically implemented, requiring no additional manual configuration.

Configuring Basic BIERv6 Functions: Configuring basic BIERv6 functions involves configuring sub-domains, BFR-prefixes, End.BIER SIDs, and BSLs for bit forwarding routers (BFRs). In addition, a BFR-ID needs to be configured for each bit forwarding egress router (BFER).

Enabling IS-ISv6 for BIERv6: If IS-ISv6 for BIERv6 is enabled on BFRs, BIFTs can be generated on the BIERv6 control plane.

(Optional) Configuring Inter-AS Static Traversal: When a BIERv6 network is deployed across ASs, static BFR-neighbors need to be configured so that static BIERv6 BIFT entries are generated. These entries enable traversal to be implemented if BIERv6-incapable nodes exist on an inter-AS path, as long as these nodes support IPv6 unicast forwarding.

Verifying the Configuration: After configuring the BIERv6 network, check the committed configurations and whether they have taken effect. In addition, perform ping operations to check the BIERv6 network connectivity, BFR reachability, and network performance indicators such as the packet loss rate and delay.
