Hello,
Am trying to create a Tunneling IPV6 VS to IPv4 RS.below are the commands i
used .
ipvsadm -A -t [fd21:d1aa:194a:3515:0:1:0:0]:80 -s rr
ipvsadm -a -t [fd21:d1aa:194a:3515:0:1:0:0]:80 -r 172.20.22.229:80 -i
root@172.20.28.92~#ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP [fd21:d1aa:194a:3515:0:1::]:80 rr
-> 172.20.22.229:80 Tunnel 1 2 0
root@172.20.28.92~#
While connecting the Virtual server, the request is not passing to the tunneled
IPV4 real server.
