Hi All,

I'm trying to set up connectivity between two sites using vpls, ldp, mpls. But i'm not getting connectivity between two sites.

I'm sure i'm doing something wrong in config. can someone please advise me where i'm mistaking.

Please find attached config file for each router.

Any advise or help would be highly appriciated. 

Thanks

Hi,

Can you check status of the VPLS connections:

show vpls connections

The CEs need to be on the LAN. Currently there are 2 different subnets.

Cheers,

Ashvin

Here it is

root@PE1# run show vpls connections
Layer-2 VPN connections:

Hi ,

Here is ping result

Hi,

The vpls shows up.

You are not able to ping because CE1 has no route to 12.12.12.12.

Could you configure CE2 WAN interface with an IP address in same range as 192.168.1.0/24 and the ping the WAN interfaces. VPLS is like an Ethernet LAN, so facing nodes need to be on the same subnet.

To ping the loopback addresses, some routing protocol [static/IGP] has to be configured.

Cheers,

Ashvin

Hi Ashvin,

I tried to configure IGP like this

CE1

protocols {
    ospf {
        area 0.0.0.1 {
            interface ge-0/0/1.0;
            interface lo0.0 {
                passive;
            }
        }
    }
}

On PE1

 ospf {
        area 0.0.0.0 {
            interface ge-0/0/2.0;
            interface ge-0/0/3.0;
            interface lo0.0 {
                passive;
            }
        }
        area 0.0.0.1 {
            interface ge-0/0/1.0;
        }
    }

Same way i have configured on CE2 and PE2 but still i'm not getting connectivity.

root@VJXT0# run ping 12.12.12.12 
PING 12.12.12.12 (12.12.12.12): 56 data bytes

How can i configured static route as CE facing interface on PE don't have ip address configured.

set routing-option route 12.12.12.12 next-hop ? (what would be the address here ?)

Thanks,

Jay

Hi , Please share :

show vpls mac-table instance CUST-A

I'm not able to do that.

root@PE1> show vpls ?      
Possible completions:
  connections          Show VPLS connections information
  flood                Show VPLS flooding information
  statistics           Show VPLS statistics information
root@PE1>  

Hi,

The IGP is to be configured between the 2 CEs.

If L3 routing is required between CE-PE, this would be an L3VPN.

In VPLS, the CE WAN interfaces should be in the same broadcast domain.

Could you configure below on CE2 and try pinging:

set interfaces ge-0/0/1.600 family inet address 192.168.1.10/24

Ping from CE2 to CE1:
> ping 192.168.1.1

As mentioned, VPLS [Virtual Private LAN service] is like an Ethernet LAN.

You could then configure OSPF on ge-0/0/1.600 interface of both CEs and the OSPF neighbor would be formed between CE1 and CE2.

Cheers,

Ashvin

Hi Ashvin,

Thanks a lot for all your help!!

Followed your solution and its working.

I have configured two sites in same LAN and i'm able to ping to physical interface now.

I have configured ospf on both CE's .600 interface and i'm able to ping to lo0 interface now.
