Active gateway is unreachable
You are unable to ping the active gateway.
-
Verify that kernel interface is created for active gateway:
003000000000001@vlan3: <NO-CARRIER,BROADCAST,UP,M-DOWN> mtu 1500 qdisc noqueue state LOWERLAYERDOWN group default qlen 1000 link/ether 00:00:00:00:00:01 brd ff:ff:ff:ff:ff:ff
-
Verify that the active gateway IP is programmed correctly on kernel interface:
003000000000001@vlan3: <NO-CARRIER,BROADCAST,UP,M-DOWN> mtu 1500 qdisc noqueue state LOWERLAYERDOWN group default qlen 1000 link/ether 00:00:00:00:00:01 brd ff:ff:ff:ff:ff:ff inet 10.0.0.3/32 scope global 003000000000001 valid_lft forever preferred_lft forever inet 20.0.0.3/32 scope global 003000000000001 valid_lft forever preferred_lft forever
-
Verify that the active gateway VMAC is correctly configured in the hardware. The command used is platform-specific. Refer to the hardware documentation for your switch.
The following example from the 8400 series switch:
8400X:/home/admin# ovs-appctl l3pd/show router-mac –a
