VPLS with IP in the vlan interface

I have this config in a Cat6500:

l2 vfi XXX manual

vpn id XXX

neighbor 1.1.1.1

interface vlan XXX

ip addrr 2.2.2.2

xconnect vfi XXX

With this config I can't reach from 6500 other equipments on this vlan with vpls.

It is ok to setup an ip address in a VLAN interface even if the interface have VPLS "xconnect" configuration?

Re: VPLS with IP in the vlan interface

Hi,

No, IP address and VPLS configuration cannot co-exist.

ANyone here who can correct me in case I am missing something?

To my knowledge following Switchport interfaces are suported:

a) Access

b) Trunk

c) dot1q-tunnel

Cheers

Re: VPLS with IP in the vlan interface

Why IP address and VPLS configuration cannot co-exist????

Re: VPLS with IP in the vlan interface

sultan is correct you cannot use IP address and Xconnect command on the same interface. I done it and TAC freaked out that you could actually do it - so its defo not supported and you will find if you upgrade your device it will not let you do it again ;-)

Thanks for you reply. But can you explain me better why don't work?

Re: VPLS with IP in the vlan interface

Hi Guys,

I would like to put my idea only but i do't know if it is correct or not.

but if we defice any ip address on the interface than this will help us to improve anything but will appear in the routing table of PE router and it could be a part of it's routing and MPLS which is not required.

secondly we are trying to emulate layer2 briedge accross the VPLS backbone not the Layer 3 switch domain. than it could be possible that you configure routing accross the backbone but there is no such kind of mechanism to enable routing.

please rate if it helps.

Re: VPLS with IP in the vlan interface

Hi Kamlesh,

There is one more thing that I would like to add here, you CAN have MP2MP connectivity without L2 bridging with RFC 2547 bis implementation.

Is our understanding correct or you meant something else when you said that routing is not possible in a L3 based VPLS "like" domain

Cheers,

Re: VPLS with IP in the vlan interface

Hi Sultan,

We both have same concept. i agree to have 2547 RFC compatible L3 VPN it works in VPLS but the requirement is to have xconnect with ip address which is not possible.

either use L2 vpls or use L3 vpls.

thanks

Re: VPLS with IP in the vlan interface

I got you. But when I configure an ip address in an interface vlan with xconnect VPLS, I can ping and use for about 3 minutes, and after this I can't ping anymore.

IT WORKS, but, for just a few minutes..

Anyone?

Re: VPLS with IP in the vlan interface

TAC told me that is a feature supported in the 7600.
