Hello, We are going to interconnect two of our datacenters. In one datacenter we have a 6880-X configured with VSS and on the other hand, we have a pair of ASR 1001-X.
We would like to configure the VPLS and I have some questions about the redundancy and loop avoidance. You can find a diagram attached to my email.. *6880 VSS : * *l2 vfi VPLS-VLAN-582 manual* * vpn id 582* * neighbor ASR-2 24 encapsulation mpls* * neighbor ASR-1 23 encapsulation mpls* *interface Vlan582* * mtu 9180* * no ip address* * xconnect vfi VPLS-VLAN-582* *ASR 1: * interface GigabitEthernet0/0/5 service instance 100 ethernet description VLAN582 encapsulation dot1q 582 exact rewrite ingress tag pop 1 symmetric bridge-domain 582 ! l2 vfi VPLS-VLAN-582 manual vpn id 582 bridge-domain 582 mtu 9180 neighbor VSS-6880 23 encapsulation mpls ! *ASR 2 : * interface GigabitEthernet0/0/5 service instance 100 ethernet description VLAN582 encapsulation dot1q 582 exact rewrite ingress tag pop 1 symmetric bridge-domain 582 ! l2 vfi VPLS-VLAN-582 manual vpn id 582 bridge-domain 582 mtu 9180 neighbor VSS-6880 24 encapsulation mpls ! At the moment, I've enabled one interface on the ASR-1 (g0/0/5), the g0/0/5 on ASR-2 is still shut. VPLS is working like a charm between the 6880 and ASR-1 but now I would like to activate the second interface on ASR-2 :-) I have some doubts about a loop in this case... I guess there should be no loop because the 6880 is configured with split-horizon but I just wanted to be sure that I will not break my network if I activate the second port. Can you please help me ? Thank you. # - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - # - - Nicolas KARP # - - Network and Security Engineer # - - Email : [email protected] <[email protected]> # - - Linkedin : http://www.linkedin.com/in/nicolaskarp # - - Viadeo : http://www.viadeo.com/fr/profile/nicolas.karp <http://www.viadeo.com/fr/profile/nicolas.karp%20> # - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
