Alcatel Unleashed

I was wondering if anybody has a sample configuration for evpn on 7750SR, I 'd like to advertise a pair of (MAC/IP) between evpn sites.

Thanks

Hi,

It's quite simple.

You have two options when creating a L2 VPN, epipe or VPLS. epipe is used to connect two sites directly and VPLS is used to connect multiple sites. I mean, if you want to connect site A to site B (and vice versa), epipe would be enough but if you want to fully meshed sites like A, B, C, Dl VPLS is your solution. Depending on your requirement, you need to choose one of those but if there is any future growth possibility, you can use VPLS.

Example configurations can be found here;

Epipe--> page 348
VPLS --> page 602

Hi,
Thanks for your reply,
What I m looking for is not vpls, because in vpls all the MAC learning process is done at data plane, which causes lots of problem like scaling issues and mac explosion. There is a new technology called EVPN which is mostly used in DCs and in general for DCI. In EVPN you can have all of a L3 service functionality for a L2 service, because MAC learning is done at control plane which gives a lot of flexibility in designing data centers. It is just one of the feature of EVPN. Alcatel has some good presentation about EVPN one of them was in APRICOT 2014 conference.
Anyway I found the solution, to transfer both MAC and IP in one advertisement in evpn, we need to use VPRN on top of the R-VPLS ( which have evpn enabled in it). In this case we can have both of IP and MAC on BGP route table.

Thanks

Hi reza,

I am looking for a lab scenario on EVPN. Is there any command reference available for EVPN? I was trying to implement BGP multihoming VPLS to show the drawbacks of it like no active-active link possible, MAC address scalability, convergence time etc. I would be very grateful to you if you can provide me with complete configuration of a BGP multihoming scenario.

PS the link shared for the configuration doesnt work for me.

Thanks in advance.
