Routing

Hi , expert i want to extend layer 2 connectivity between my two sites over service provider network. Hence concept is new to me so i tried to implement test scenario given at link http://www.juniper.net/techpubs/en_US/junos11.4/topics/example/mpls-ex-series-configuring.html.

My test scenario is attached, done configuration as per guidelines in above link moreover  status for OSPF, MPLS and Connections are good (see attachment)  I am trying to ping booths PC's from each other but unable to ping .

Any guidance please.

Hi Route champ,

Here are the steps for Configuring the Connection for l2vpn connectivity

With circuit cross connection vlan translation does not work for remote interface switch. Translational works  only for local switching. >>>> are you taking care of this??

neteng@JUNIPER_26# show protocols connections

remote-interface-switch REMOTE_SWITCH {

   interface ge-1/0/4.11;

   transmit-lsp TO-R4;

   receive-lsp TO-R6;

}

May i know the reason for using this lagcy solution? configuration is quit simple and there should not be any issue.

Thanks for reply , my configuration for connection are on the same lines as you have advised but what protocol family should be configure for interface ge-1/0/4.11 , my configuration for interface is as :- set interface ge-0/0/4 unit 0 family ccc this is the local interface where my PC is connected  and same configuration is done on remote end where other PC is connected.

You will need to explicitly configure encapsulation:

1/ case #1 - PWE type 5, port-based 

set interfaces ge-0/0/4 encapsulation ethernet-ccc

 2/ case #2 - PWE type 4, VLAN-based

set interfaces ge-0/0/4 encapsulation extended-vlan-ccc

 HTH

Thanks

P.S. Frequently asked question is "why different encapsulation is needed for CCC, this is Ethernet, I want it to be same and simple". The answer is "go join IETF and make a standard for self, since L2circuit headend STRIPS the Ethernet FCS before sending a frame into a PWE, this is CURRENT STANDARD". See http://tools.ietf.org/html/rfc4448 section 4.4

Hence DIFFERENT encapsulation is required for CCC/L2circuit/PWE.

Hi Route champ,

As you are directly connecting laptop (in default configuration laptop accept untagged frames) to the PE device, so your configuration on the interface will be

"set interfaces ge-0/0/4 encapsulation ethernet-ccc".

Thank again for reply , actually i am using EX 4200 as Provider Edge router, set interface ge-0/0/1 ? does not provide encapsualtion option here, so what to do now

HI Satinder and aarseniev thanks for reply, on Ex 4200 encapsulation option was not available but i have arranged SRX 210 on which encapsulation option is available
