So I’m very new to OSPF and MPLS and VPLS, just switched our bridged network to routed and these have made it really simple for the switchover. I have VPLS working but id like to have it set up correctly as in best practices and 1:1 and 2:2 and 3:3 don’t cut it.
Can anyone break it down a little more? Sorry every thing I’ve learned is self taught and the VPLS id seems to be very vague in documentation besides this breakdown. Any links that describe this in more detail would be much appreciated.
I use the loopback ip:site id (same as ibgp as number) and if a router have more than one tunell, just take the next number (last octet) to next tunnel.
eg my router at site 14 will be:
loopback : 172.31.0.14
bgp as nr: 14
vpls id 172.31.0.14:14
router at site 175:
loopback: 172.31.0.175
bgp as nr: 175
vpls id 172.31.0.175:175
Also used to id in MPLS lsr-id and transport, ospf routerid and “all places” that need an id setting.
(and yes, its possible to have more than 255, just start at 172.31.1.xxx)
Ideally, you should use one of these [quote=wikipedia] The Internet Assigned Numbers Authority (IANA) has designated AS numbers 64512 through 65534 to be used for private purposes.[/quote]
EDIT: AS number is the assigned number of your autonomous system. Most people do not have one , so use one of the abovementioned private ones.
@samsung172 - So in area1 router 19 (172.1.100.19), I need access to the PPPoE Concentrator, so I VPLS tunnel from router to the concentrator (172.1.100.1), I would structure the VPLS ID as EDIT: 19:172.1.100.19 correct?
It does not matter. But its a lot more easier to follow the id setting plan. if you get many tunnels, it can be difficult to have all with random numbers.
, so use one of the abovementioned private ones.
