IGP-Metric-Based AIGP Path Selection for Flex-Algo Topologies

You can use IGP metrics for AIGP path selection in SR-MPLS networks with flex-algorithm topologies, ensuring consistent low-latency routing across domains with different metric types. You can enable IGP metric computation for a flex-algorithm topology using the [compute-igp-metric] statement and assign multiple colors to a flex-algorithm with the [secondary-color] statement, both configured under [routing-options flex-algorithm ]. 

For finer control over route resolution, import policies can be managed within resolution schemes by using [import-policy-append] to add policies or [import-policy] to replace existing ones, configured under [routing-options resolution scheme ]. 

Additionally, policy statements now support the [actual-igp-cost] metric expression keyword, which allows precise adjustment of IGP metrics during route selection and is configured within [policy-options policy-statement ].
