However during the investigation I find the MPLS feature pack is marked: IPV4 only.<BR /> Is it mean MPLS over IPV6 is not supported in the newest OS?<BR /> <BR /> Thanks for the reply!<BR /> <BR /> Nan<BR /> <BR /> Fri, 03 Jul 2015 10:58:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/does-exos-support-mpls-over-ipv6/m-p/27888#M4159 nan_zhang 2015-07-03T10:58:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/does-exos-support-mpls-over-ipv6/m-p/27889#M4160 Nan Zhang,<BR /> <BR /> That is correct.
