Pre-established BGP connection to HA?

L0 Member

All,
I'm looking to set up established BGP connections from the upstream routers (Cisco Nexus) to the HA unit in our A/P setup for faster failover times, and to not make it look weird when trying to determine if adjacencies are up to the primary unit from the router side. I know there's some things that can be established, LACP and the like, but don't see an option for BGP anywhere. Is there a way to do this, or is this not a good idea? What other optimizations should be run in A/P BGP setup to ensure a fast failover to the HA unit? I've seen mention of BFD but haven't tried this yet, I'm curious to see if that helps me out. To be clear, I haven't tested failover yet, so I don't know if this is an issue that I'm trying to solve before it's a problem. Thanks for the help, looking forward to some good answers!

Hi @jbraswell32 ,

 

With regard to A/P HA, BGP Graceful Restart (GR) is recommended for faster failover.

The GR feature is designed to keep the BGP neighbor from dropping and routes continuing to forward during the failover process.

 

Thanks,

 

Tom
