Step 5
rewrite ingress tag pop symmetric
Example:
Router(config-if-srv)#rewrite ingress
tag pop 1 symmetric
Specifies the tag manipulation that is to be performed on the frame
ingress to the service instance.
Note If this command is not configured, then the frame is left intact
on ingress (the service instance is equivalent to a trunk port).
Step 6
bridge-domain vlan id split-horizon id
Example:
Router(config-if-srv)# bridge-domain 1
split-horizon group 0
Enables RFC 1483 split horizon mode to globally prevent bridging.
Step 7
interface Ethernet-Internal slot /0/0
Example:
Router(config)# interface
Ethernet-Internal 2/0/0
Configures the second Cisco SM-X Layer 2/3 ESM (ESM1).
Step 8
service instance id ethernet
Example:
Router(config-if)# service instance 1
ethernet
Creates a service instance on an interface and enters service instance
configuration mode.
Step 9
encapsulation vlan id dot1q
[second-dot1q vlan id ]
Example:
Router(config-if-srv)# encapsulation
dot1q 20
Defines the encapsulation type and enables IEEE 802.1Q encapsulation
of traffic on a specified subinterface in a VLAN. See details in Step 4
Step 10
rewrite ingress tag pop symmetric
Example:
Router(config-if-srv)# rewrite ingress
tag pop 1 symmetric
Specifies the tag manipulation that is to be performed on the frame
ingress to the service instance.
Note If this command is not configured, then the frame is left intact
on ingress (the service instance is equivalent to a trunk port).
Step 11
bridge-domain vlan id split-horizon id
Example:
Router(config-if-srv)# bridge-domain 1
split-horizon group 0
Enables RFC 1483 split horizon mode to globally prevent bridging.
Step 12
interface BDI interface number
Example:
Router(config)# interface BDI 1
Specifies a bridge domain interface.
