Subject: [pve-devel] [PATCH] controllers: bgp: enable multihop on the underlay
Date: Fri, 9 Apr 2021 14:21:37 +0200 [thread overview]
Message-ID: <20210409122137.9557-1-px@jack.fr.eu.org> (raw)
From: Alexandre Bruyelles <git@jack.fr.eu.org>
Multihop is required when the bgpd are running across
a pair of MLAG routers.
In such scenario, TCP trafic from Proxmox to router A
may pass through router B, which will decrease the TTL.
