Cisco CSR1000v#

Cisco CSR1000v virtualized router is identified with vr-csr kind in the topology file. It is built using vrnetlab project and essentially is a Qemu VM packaged in a docker container format.

vr-csr nodes launched with containerlab comes up pre-provisioned with SSH, SNMP, NETCONF and gNMI services enabled.

Managing vr-csr nodes#

Note

Containers with CSR1000v inside will take ~6min to fully boot.
You can monitor the progress with docker logs -f <container-name>.

Cisco CSR1000v node launched with containerlab can be managed via the following interfaces:

to connect to a bash shell of a running vr-csr container: 

docker exec -it <container-name/id> bash

to connect to the CSR1000v CLI 

ssh [email protected]<container-name/id>

NETCONF server is running over port 830 

ssh [email protected]<container-name> -p 830 -s netconf

Info

Default user credentials: admin:admin

Interfaces mapping#

vr-csr container can have up to 144 interfaces and uses the following mapping rules:

  • eth0 - management interface connected to the containerlab management network
  • eth1 - first data interface, mapped to first data port of CSR1000v line card
  • eth2+ - second and subsequent data interface

When containerlab launches vr-csr node, it will assign IPv4/6 address to the eth0 interface. These addresses can be used to reach management plane of the router.

Data interfaces eth1+ needs to be configured with IP addressing manually using CLI/management protocols.

Features and options#

Node configuration#

vr-csr nodes come up with a basic configuration where only admin user and management interfaces such as NETCONF provisioned.
