How to Configure Remote Loop-Free Alternate - Fast Reroute
Step 4
no negotiation auto
Example:
Router(config-if)# no negotiation auto
Disables automatic negotiation.
Step 5
service instance
id
ethernet
Example:
Router(config-if)# service instance 7
ethernet
Configures an Ethernet service instance on an interface.
• id—Integer that uniquely identifies a service instance on an
interface.
Step 6
encapsulation dot1q
vlan-id
Example:
Router(config-if)# encapsulation dot1q
7
Enables IEEE 802.1Q encapsulation of traffic on a specified
interface in a VLAN.
• vlan-id—Virtual LAN identifier.
Step 7
rewrite ingress tag pop 1 symmetric
Example:
Router(config-if)# rewrite ingress tag
pop 1 symmetric
Specifies the encapsulation adjustment to be performed on a frame
ingressing a service instance.
• pop—Removes a tag from a packet.
• 1—Specifies the outermost tag for removal from a packet.
• symmetric—Indicates a reciprocal adjustment to be done in the
egress direction. For example, if the ingress pops a tag, the
egress pushes a tag and if the ingress pushes a tag, the egress
pops a tag.
Step 8
bridge-domain
bridge-domain-id
Example:
Router(config-if)# bridge-domain 7
Enables RFC 1483 ATM bridging or RFC 1490 Frame Relay
bridging to map a bridged VLAN to an ATM permanent virtual
circuit (PVC) or Frame Relay data-link connection identifier
(DLCI).
• bridge-domain-id—Bridge domain identifier.
Step 9
interface vlan
bridge-domain-id
Example:
Router(config-if)# interface vlan 7
Configures an Ethernet interface to create or access a dynamic
Switch Virtual Interface (SVI).
Step 10
ip address
ip-address
Example:
Router(config-if)# ip address 7.7.7.1
255.255.255.0
Specifies an IP address for the specified interface.
Step 11
ip router isis
Example:
Router(config-if)# ip router isis
Configures an IS-IS routing process for an IP on an interface.
Step 12
mpls ip
Example:
Router(config-if)# mpls ip
Enables MPLS forwarding of IPv4 packets along normally routed
paths for a particular interface.
