Chapter 5 Cisco ASR 1001-X Router Power Up and Initial Configuration
Performing the Initial Configuration on the Router
Default Gigabit Ethernet Configuration
By default, a forwarding VRF is configured for the interface with a special group named Mgmt-intf. This
cannot be changed. This isolates the traffic on the management interface away from the forwarding
plane. Otherwise, the interface can be configured like other Gigabit Ethernet interfaces for most
functions.
For example, the default configuration is as follows:
interface GigabitEthernet0
vrf forwarding Mgmt-intf
ip address 172.18.77.212 255.255.255.240
negotiation auto
Configuring Gigabit Ethernet Interfaces

For comprehensive configuration information on Gigabit Ethernet interfaces, see the “Configuring LAN
Interfaces” chapter of the Cisco IOS Interface and Hardware Component Configuration Guide.
For information on interface numbering, see the software configuration guide pertaining to your router.
