Ping to vIP using vMAC fails in a VRRP scenario

[Ganesha HV]

Build CentOS release 6.5 2.10-42~havana.el6

Configure VRRP on the VMs as below :

nohup vrrpd -D -i eth0 -v 1 -a none -p 20 -d 3 10.10.10.10

Create 2 VMs and enable VRRP between them, specifying a vIP.
Update the ports of the respective VMs to allow the vIP so configured.

Ping to the vIP using vMAC is failing.

Praveen is aware of the issue.

contrail-vrouter-agent doesn't install EVPN route for AAP if mac is specified.
Hence layer2 route for the vMAC would not be present, if VM originates
a packet with vMAC packets would be discarded because of layer 2 route table
look up failure.

Changes to be done in contrail-vrouter-agent:
1> Agent should advertise EVPN route for AAP if mac is specified.
2> Agent should run mastership algorithm for EVPN route based on
      VM originating active traffic for given AAP.

Whenever mastership flap happens there would be temporary ecmp route,
since there would be 2 path with high preference, with the latest master
publishing the path with higher sequence no than the old master.
In case of unicast route both the path would goto backup state after
publishing path with low preference and run mastership election again,
new master would publish again with high preference.
Instead of this transition proposal is for control-node to path with highest sequence,
which would avoid ECMP routes for EVPN.

Include sequence number in ECMP decision

Support for ESIs will be added in future. This change should be
good enough to get things working for currently supported cases.

Not overwriting VM's Mac in L2 encap nh

In R2.1, while supporting Floating IP, Agent on Private Network side
used to advertise Evpn route of Floating IP by stitching to Vhost's MAc.
Because of this to the reverse flow packets come to to compute node with
Vhosts mac and this mac is converted to VM's MAC, by l2 rewrite data.
But this overwrite is no more necessary as Agent started stiching this
IP with VM's MAC. So removing this rewrite data for L2 encap NH.
