[c-nsp] l2tpv3 Issues on 6800/3800

[Harivishnu Abhilash]

Thanks for the response. But we were quite surprised as the 6800 was doing EoMPLS perfectly. We had to do L2tpV3  as  we shifted the role of the mpls device to non-mpls (sort of a migration from a PE role to CE for design requirements) and more over we are only extending a peering VLAN to get the IBGP between to routers up (like a backup path)

Hi,

First things first : DON'T !
More precisely (for the impact) : https://www.packetmischief.ca/wordpress/wp-content/uploads/2013/04/failure-domain-atomic-bomb.jpg
.. and the related post : https://www.packetmischief.ca/2013/04/02/why-is-there-a-wrong-way-to-interconnect-datacenters/

That being sorted out, 6800 is a switch and should not be expected to do l2tpv3. Same for the 3850, if this is what you mean by "3800". You may try you luck with GREP (Ethernet over GRE), but support on 3850 is "variable" at best (starting with "not supported" - depending on OS version).
