I'm looking to find out what is the best practice in MCT implementation for maintaining uplink redundancy with line card failures.
I'm running 2x MLXe/8 at edge each with one uplink to different geographic region routed by BGP4.
I need a solution that will account for both a bad uplink and a failed line card on the opposing MCT partner router.
How should I be handling the uplink routing to that opposing partner?
MCT Cluster (MLX1 & MLX2). Downstream connections are all LACP to both nodes.
MLX1 uplinks to loc A and MLX2 uplinks to loc B.
If I have a failure of uplink at loc B and a bad line card(for downstream connections) on MLX1, how can I tell traffic that's destined for upstream that arrives from downstream on MLX2 to cross the ICLs and use the uplink at MLX1? Run iBGP across ICLs?
