Hi Folks,
I'm seeing something odd when trying to use two 'br-ext' (one called
br-ext, network_name=physnet
and one called br-drg, network_name drgnet) connected to br-int, when I
try schedule a gateway
with Distributed Router port on to three chassis. My ovn-bridge-mappings
is set as follows:
ovn-bridge-mappings="physnet:br-ext,drgnet:br-drg"
The DR Port does not get scheduled I get an error in the ovn-controller
log of:
ERR|localnet port 'ln-ls_vcn2_external_drg' has no network name.
Any thoughts? There are two odd things about this
1) The error is seen not on the chassis with the highest priority, but
on the chassis with the second highest.
# ovn-nbctl list gateway_chassis

Error is seen on sca15-rain06.
2) The localnet port does have a network_name:

just the one where the
DR port should have been scheduled, and the one where an attempt to
schedule it was made):
