The picture below shows the topology configured.<BR /> PE11 and PE12 are X670-G2 and PE13 is X460-G2.<BR /> <BR /> <BR /> <P class="fancybox-image"><span class="lia-inline-image-display-wrapper" image-alt="24f4485b23984b60949fcba401d72c92_a6be5aac-cfd8-4302-956f-77bd68db1812.png"><img src="https://community.extremenetworks.com/t5/image/serverpage/image-id/2486iCDBD849C8F893799/image-size/large?v=v2&amp;px=999" role="button" title="24f4485b23984b60949fcba401d72c92_a6be5aac-cfd8-4302-956f-77bd68db1812.png" alt="24f4485b23984b60949fcba401d72c92_a6be5aac-cfd8-4302-956f-77bd68db1812.png" /></span></P><BR /> I've configured MPLS, LDP, OSPF and the L3VPN seems to work fine. But, when I tried to configure VPLS, I can't make the tunnel up among all nodes.<BR /> <BR /> The VPLS was configured in all equipiments, but the VPLS is established only inside the domain and from switches located on the border of domain<BR /> <BR /> Examples:<BR /> - Looking from PE11 on Extreme domain, the VPLS is up only for the neighboors PE12 and PE13. <BR /> - Looking from PE12, besides PE11 and PE13, the tunnel becomes up to PE1 of Huawei domain. <BR /> - The tunnel is down from PE11 to all Huawei domain.<BR /> - The same happens from Huawei domain. Looking from PE2, the VPLS becomes up for its neighboors PE1 and PE3, but not for any equipment from Extreme domain. <BR /> - From PE1, the VPLS is up for all Huawei domain and for PE12 of Extreme domain.<BR /> - The VPLS is not established between PE2 and PE11 edges.

You can also put the service VLAN in loopback-mode which should activate the VPLS (enable loopback-mode vlan X)<BR /> <BR /> Rgds,<BR /> Mikael Tue, 09 Apr 2019 12:19:58 GMT https://community.extremenetworks.com/t5/network-architecture-design/vpls-between-x670-x460-g2-not-working-with-huawei-s5720/m-p/83518#M2647 Holmberg__Mikae 2019-04-09T12:19:58Z https://community.extremenetworks.com/t5/network-architecture-design/vpls-between-x670-x460-g2-not-working-with-huawei-s5720/m-p/83519#M2648 Hi Mikael,<BR /> <BR /> I've enabled loopback mode on a vlan service in all Extreme nodes.
