Why I did it
Fix support for DHCPV6 Relay multi vlan functionality. Make sure the relayed packet is received at correct interface.
How I did it
Bind a socket to each vlan interface's global and link-local address.
Socket binded to global address is used for relaying data from client to server and receiving data from servers.
Socket binded to link-local address is used for relaying data received from server back to the client.
How to verify it
Build a image and run two_vlan dhcpv6 tests.
