Chapter 21 Configuring Pseudowire
Configuring Pseudowire
Step 9
controller {e1|t1}
slot/port
Example:
Router(config)# controller e1 0/0
Enters E1/T1 controller configuration mode.
Step 10
cem-group
number
timeslots
number
Example:
Router(config-controller)#
cem-group 5 timeslots 1-24
Assigns channels on the T1 or E1 circuit to the CEM channel. This
example uses the unframed parameter to assign all the T1 timeslots to the
CEM channel.
Step 11
exit
Example:
Router(config-controller)# exit
Exits controller configuration.
Step 12
interface cem
slot/port
Example:
Router(config)# interface CEM 0/5
Selects the CEM interface where the CEM circuit (group) is located
(where slot/subslot is the SPA slot and subslot and port is the SPA port
where the interface exists).
Step 13
no ip address
Example:
Router(config)# no ip address
Disables the IP address configuration for the physical layer interface.
Step 14
cem
group-number
Example:
Router(config-if)# cem 5
Defines a CEM channel.
Step 15
xconnect
peer-router-id vcid
{pseudowire-class
name
}
Example:
Router(config-if-cem)# xconnect
30.30.30.2 305 pw-class udpClass
Binds an attachment circuit to the CEM interface to create a pseudowire.
This example creates a pseudowire by binding the CEM circuit 5 to the
remote peer 30.30.30.2.
Note When creating IP routes for a pseudowire configuration, we
recommend that you build a route from the cross-connect address
(LDP router-ID or loopback address) to the next hop IP address,
such as ip route 30.30.30.2 255.255.255.255 1.2.3.4.
Step 16
udp port local
local_udp_port
remote
remote_udp_port
Example:
Router(config-if-cem-xconn)# udp
port local 49150 remote 55000
Specifies a local and remote UDP port for the connection. Valid port
values for CESoPSN pseudowires using UDP are from 49152–57343.
Step 17
end
Example:
Router(config-if-cem)# end
Exits the configuration mode.
