Hi,
I'm looking for a way to manage an ASR 9K via inband and outband.
Via inband is easy. But how does an configuration looks like for outband?
I tried the following:
vrf MGMT
address-family ipv4 unicast
interface MgmtEth0/RSP0/CPU0/0
vrf MGMT
ipv4 address 10.1.1.53 255.255.255.0
!
interface MgmtEth0/RSP0/CPU0/1
shutdown
!
interface MgmtEth0/RSP1/CPU0/0
vrf MGMT
ipv4 address 10.1.1.54 255.255.255.0
!
interface MgmtEth0/RSP1/CPU0/1
shutdown
!
ipv4 virtual address vrf MGMT 10.1.1.52/24
router static
vrf MGMT
address-family ipv4 unicast
0.0.0.0/0 10.1.1.1
!
!
!
telnet vrf MGMT ipv4 server max-servers 5
telnet vrf default ipv4 server max-servers 10
telnet ipv4 client source-interface Loopback0
I can connect to 10.1.1.53 or 54, but not to 10.1.1.52.
Any help?
Regards, Celio

You would probably be better off putting a new Loopback into the VRF and using that as the primary management interface. Using a Loopback such as Lo1 and putting it into the VRF could also assist with monitoring.
A good design would have BGP binding to Lo0 for routing, and all management traffic including Telnet, SSH, SNMP, etc. going through the Lo1 / VRF.

Hi Celio,
SystemFailure0x5a has a good proposal.
You could also try this:
"ipv4 virtual address"

Hello,
A doubt I have had is the purpose of the second management interface on each RP. All configurations I have seen that interface is shutdown.
Does this interface can be used in the same subnet to provide further redundancy, or it has to be in a different subnet and can have a second ip virtual address in that subnet.

Yes, no problem with that. You can configure both management interfaces in the same subnet if you want. Just make sure each interface has a unique IP address. Also make sure to read my comment below.
