Juniper ACX2000 Configuration Guide

The pseudowire between Device PE1 and Device PE3 is the primary or working path. The
pseudowire between Device PE1 and Device PE2 is the backup path.
To support VLANs with H-VPLS, you must include the output-vlan-map swap statement
in the configuration of the MTU device as a workaround to prevent a VLAN ID mismatch.
Otherwise, the PE-r devices report a VLAN ID mismatch, as shown here:
user@PE2> show vpls connections
Layer-2 VPN connections:
Legend for connection status (St)
EI -- encapsulation invalid NC -- interface encapsulation not CCC/TCC/VPLS
EM -- encapsulation mismatch WE -- interface and instance encaps not same
VC-Dn -- Virtual circuit down NP -- interface hardware not present
CM -- control-word mismatch -> -- only outbound connection is up
CN -- circuit not provisioned <- -- only inbound connection is up
OR -- out of range Up -- operational
OL -- no outgoing label Dn -- down
LD -- local site signaled down CF -- call admission control failure
RD -- remote site signaled down SC -- local and remote site ID collision
LN -- local site not designated LM -- local site ID not minimum designated
RN -- remote site not designated RM -- remote site ID not minimum designated
XX -- unknown connection status IL -- no incoming label
MM -- MTU mismatch MI -- Mesh-Group ID not available
BK -- Backup connection ST -- Standby connection
PF -- Profile parse failure PB -- Profile busy
RS -- remote site standby SN -- Static Neighbor
LB -- Local site not best-site RB -- Remote site not best-site
VM -- VLAN ID mismatch
Legend for interface status
Up -- operational

“CLI Quick Configuration” on page 1312 shows the configuration for all of the devices in
Figure 68 on page 1311. The section “Step-by-Step Procedure” on page 1314 describes the
steps on Device PE1 and Device PE2.

Configuration
To quickly configure this example, copy the following commands, paste them into a text
file, remove any line breaks, change any details necessary to match your network
configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy
level.
Device PE1 set interfaces ge-2/0/5 vlan-tagging
set interfaces ge-2/0/5 encapsulation vlan-ccc
set interfaces ge-2/0/5 unit 601 encapsulation vlan-ccc
set interfaces ge-2/0/5 unit 601 vlan-id 601
set interfaces ge-2/0/5 unit 601 output-vlan-map swap
set interfaces ge-2/0/5 unit 601 family ccc
