2017.11.18 – XRv Intial Configuration

The IOS XRv router is allready installed in my MacBook as detailed into my recent article Cisco IOS XRv on VMWare Fusion.

As I need a serial connection every time I want to change my LAB setup, I’ve defined my XRv serial connection into Secure CRT as described in the last section of my recent article SecureCRT to XRv Serial Console

0. XRv Network Connectivity

Next I will provide initial configuration for the IOS XRv router to make sure it match the management network design defined for SkyLifter Project.

Network Connected Device Device Port Info IP
vmnet3 XRv Mg0/0/CPU0/0 OoB MNG Net
vmnet4 XRv-n, n=[1,n] Gi0/0/0/0 Intelink with/without VLANs not configured
vmnet7 XRv-n, n=[1,n] Gi0/0/0/1 Intelink with/without VLANs not configured

As I am new to XRv I will use the Workbook on Cisco Website.

Note: In this moment I don’t know if I can run multimple XRv instances on my MacBook.

The logical network diagram

1. I add the needed networks to XRv VM

From Fusion application, click Ubuntu VM, go to Virtual Machine > Settingsā€¦and add the needed networks.

Then start XRv VM.

2. Connect to XRv Router

I will connect using intial configured user silvia and pass silvia.

Murgescus-MacBook-Pro:~ silvia$ telnet 9001
Connected to localhost.
Escape character is '^]'.

3. Identify physical interfaces

I have defined only 4 physical interfaces which can bee seen into show interface brief command output.

RP/0/0/CPU0:XRv1#show interface bref
Fri Nov 17 19:43:15.580 UTC

Intf Intf LineP Encap MTU BW
 Name State State Type (byte) (Kbps)
 Nu0 up up Null 1500 0
 Mg0/0/CPU0/0 up up ARPA 1514 0
 Gi0/0/0/0 admin-down admin-down ARPA 1514 1000000
 Gi0/0/0/1 admin-down admin-down ARPA 1514 1000000
 Gi0/0/0/2 admin-down admin-down ARPA 1514 1000000

Note: The Mg0/0/CPU0/0 interface is an out-of-band (OOB) management interface. This will always be the first interface associated with the XRv VM as indicated in the XRv installation guide.

4. Configure Management Interface

RP/0/0/CPU0:XRv1#configure terminal 
Fri Nov 17 19:46:42.335 UTC
RP/0/0/CPU0:XRv1(config)#interface M
MgmtEth Multilink 
RP/0/0/CPU0:XRv1(config)#interface MgmtEth 0/0/CPU0/0 
RP/0/0/CPU0:XRv1(config-if)#no shut
RP/0/0/CPU0:XRv1(config-if)#ipv4 address
Fri Nov 17 19:48:37.628 UTC

RP/0/0/CPU0:XRv1#show ipv4 interface brief 
Fri Nov 17 19:49:43.543 UTC

Interface IP-Address Status Protocol
MgmtEth0/0/CPU0/0 Up Up 
GigabitEthernet0/0/0/0 unassigned Shutdown Down 
GigabitEthernet0/0/0/1 unassigned Shutdown Down 
GigabitEthernet0/0/0/2 unassigned Shutdown Down

5. I check the management connectivity from macOS Local Shell

Let’s try a ping:

Murgescus-MacBook-Pro:~ silvia$ ping
PING ( 56 data bytes
64 bytes from icmp_seq=0 ttl=255 time=3.392 ms
64 bytes from icmp_seq=1 ttl=255 time=0.471 ms
--- ping statistics ---
2 packets transmitted, 2 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.429/1.187/3.392/1.273 ms

Now telnet, as remember that ssh is not working on macOS Sierra:

Murgescus-MacBook-Pro:~ silvia$ telnet 
Connected to
Escape character is '^]'.

Perfect! Now I will be able to connect to management port using telnet into SecureCRT application.

Note: At the moment both vMX and XRv are UP and Running on my MacBook.
