Hi.
We got a freebsd router with both ospf/bpg and multipath routes
(ECMP) (using the new bird2 with netlink) .
The router got an interface with carp enabled on it (gateway for
admin vlan).
Packets received on the carp address gets routed on all known routes
towards destination. Thus, the destination host receives duplicates
ip packets. (which disrupts most udp based protocols)
Using a simple alias instead of carp solve the problem. Is this a
known problem, or should I fill a PR ?
No, that’s not a known problem.
Please do open the PR with details.
