Explanation of Juniper ping output:

The following characters can appear in the display after issuing the ping command:

* !—Reply received
* .—Timed out while waiting for a reply
* ?—Unknown packet type
* A—Address mask request message
* a—Address mask reply message
* D—Router discovery advertisement message
* d—Router discovery request message
* H—Host unreachable
* I—Information request message
* i—Information reply message
* L—TTL expired message
* M—Could not fragment, DF bit set
* m—Parameter problem message
* N—Network unreachable
* P—Protocol unreachable
* Q—Source quench
* r—Redirect message
* T—Timestamp request message
* t —Timestamp reply message
* U—Destination unreachable

MEF E-Line, E-LAN, E-Tree VPN

What are the JuniperNetworks solutions forMetro Ethernet Forum (MEF) 6.1 Ethernet services definitions, including Ethernet private line, Ethernet virtual private line, Ethernet LAN, Ethernet lines, and Ethernet trees?

• Ethernet private line (EPL) and Ethernet virtual private line (EVPL) are emulated by Juniper Networks Layer 2 circuit and Layer 2 VPN configurations.

• Ethernet LAN(E-LAN) is emulated by any Juniper Networks VPLS configuration solution.

• Ethernet lines (E-Line) service is emulated by using Juniper Networks Layer 2 circuit service configuration. The encapsulation type for the E-Line can be full Ethernet or only VLAN.

• Ethernet trees (E-Tree) service can be built using point-to-multipoint, or a more sophisticated implementation can be built using hub-and-spoke communities with BGP VPLS.

CCC between Juniper EX and MX

Topology
ge-1/0/19 family ccc <--- ---="" ex=""> ge-1/1/0 -- OSPF/MPLS/
RSVP --- ge-0/2/5 <--- ---="" mx=""> ge-0/0/8.234 family ccc

Design:
The following configuration will encapsulate all traffic from EX interface ge-1/0/19 into LSP path pushing label
299792, and this traffic will egress MX ge-0/0/8.234 tagged with vlan 234. Q-in-Q was also tested and was working.
