Fix sonic-net/SONiC#551 When eth0 IP address is configured, an ip rule is getting added for eth0 IP address through the interfaces.j2 template. This eth0 ip rule creates an issue when VRF (data VRF or management VRF) is also created in the system. When any VRF (data VRF or management VRF) is created, a new rule is getting added automatically by kernel as "1000: from all lookup [l3mdev-table]". This l3mdev IP rule is never getting deleted even if VRF is deleted. Once if this l3mdev IP rule is added, if user configures IP address for the eth0 interface, interfaces.j2 adds an eth0 IP rule as "1000:from 100.104.47.74 lookup default ". Priority 1000 is automatically chosen by kernel and hence this rule gets higher priority than the already existing rule "1001:from all lookup local ". This results in an issue "ping from console to eth0 IP does not work once if VRF is created" as explained in Issue 551. More details and possible solutions are explained as comments in the Issue551. This PR is to resolve the issue by always fixing the low priority 32765 for the IP rule that is created for the eth0 IP address. Tested with various combinations of VRF creation, deletion and IP address configuration along with ping from console to eth0 IP address. Co-authored-by: Kannan KVS <[email protected]>
