Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide
In dual RP configurations, however, users should never configure the IP address in the ROMmon on
either RP0 or RP1 to match each other or the IP address as defined by the IOS CLI. Configuring matching
IP addresses introduces the possibility for an active and standby Management Ethernet interface having
the same IP address with different MAC addresses, which will lead to unpredictable traffic treatment.
Gigabit Ethernet Management Interface VRF
The Gigabit Ethernet Management interface is automatically part of its own VRF. This VRF, which is
named “Mgmt-intf,” is automatically configured on the Cisco ASR 1000 Series Router and is dedicated
to the Management Ethernet interface; no other interfaces can join this VRF. Therefore, this VRF does
not participate in the MPLS VPN VRF or any other network-wide VRF.
Placing the management ethernet interface in its o
wn VRF has the following effects on the Management
Ethernet interface:
• Many features must be configured or used inside the VRF, so the CLI may be different for certain
Management Ethernet functions on the Cisco ASR 1000 Series Routers than on Management
Ethernet interfaces on other routers.
• Prevents transit traffic from traversing the router. Because all of the SPA interfaces and the
Management Ethernet interface are automatically in different VRFs, no transit traffic can enter the
Management Ethernet interface and leave a SPA interface, or vice versa.
• Improved security of the interface. Because the Mgmt-intf VRF has its own routing table as a result
of being in its own VRF, routes can only be added to the routing table of the Management Ethernet
interface if explicitly entered by a user.
The Management Ethernet interf
ace VRF supports both IPv4 and IPv6 address families.
Common Ethernet Management Tasks
Because users can perform most tasks on a router through the Management Ethernet interface, many
tasks can be done by accessing the router through the Management Ethernet interface.
This section documents tasks that might be common or slightly tricky on the Cisco ASR 1000 Series
Ro
uters. It is not intended as a comprehensive list of all tasks that can be done using the Management
Ethernet interface.
