Hello to everyone,
I am having an issue when trying to apply multiple paths on a running
VPP to 3 other VPPs.
Specifically after 2 paths are up when I add the 3rd path one or both
the first two stop working. I am using these commands:
/
/
/sudo vppctl -s /run/vpp/cli-vpprouter1.sock ip route add 48.0.0.0/8 via
10.10.3.2/
/sudo vppctl -s /run/vpp/cli-vpprouter1.sock ip route add 48.0.0.0/8 via
10.10.6.2/
/sudo vppctl -s /run/vpp/cli-vpprouter1.sock ip route add 48.0.0.0/8 via
10.10.12.2/
On the same subject I have an issue when trying to set different weights
on a 2 route path. As suggested on this
doc
https://docs.fd.io/vpp/21.01/de/db4/clicmd_src_vnet_ip.html#clicmd_ip_route
I use:
/sudo vppctl -s /run/vpp/cli-vpprouter1.sock ip route add 48.0.0.0/8 via
10.10.3.2 weight 9//
/
//
/sudo vppctl -s /run/vpp/cli-vpprouter1.sock ip route add 48.0.0.0/8 via
10.10.6.2 weight 1 /
but the traffic on weight 1 route is not the 1/10 of the total traffic,
more like 4/10 of it. And that's the good scenario. When traffic
gets elevated VPP sends most of the traffic on the path with the lower
value rather than what I expected it to do.
All vpps are connected through memif sockets.
Can anyone help me with any of these issues? Is it me I am doing
something extremely wrong?
