Management IP addresses are as below Device
I Topology management network is set to ‘Shared flat network’ so with configured bridging it’s externally accessible.I’ve modified VIRL configuration a little so not whole subnet is used for dynamic allocation for nodes. Firewall has IP address of 172.16.1.1, VIRL host has IP 172.16.1.254, rest of devices have management IP addresses statically configured in topology so they don’t change. It’s using predefined VIRL subnet 172.16.1.0/24.
CISCO ASAV REST API PC
Flat-1 network (eth1 interface) is bridged on dedicated NIC on my PC which is connected to my switch and firewall on dedicated VLAN. My VIRL is connected to dedicated segment of my home network so it’s accessible not only from computer where I ran VIRL – that helps when I want to test something remotely.

CISCO ASAV REST API PASSWORD
Login to all devices is ‘cisco’ with password ‘cisco’. Path from lxc-sshd-5 to lxc-sshd-7 is via asav-2 while path from lxc-sshd-6 to lxd-sshd-8 is via asav-3. Static routing is configured on this stage providing proper connectivity. Management interfaces are from network 172.16.1.0/24. All link addresses are from 10.0.0.0/8 network block (subnetted to /24 each) using 0 on second octet for link between firewalls and 100 on links to lxc hosts. Third octet of link IP address consist of node number from both ends starting with lower one, last octet is device number. Interface configuration is using addressing approach known from CCIE labs – each device has unique number. ASAv is running image 9.5(2)204 which has preinstalled ASDM 7.5(2) and REST API version 1.2.2.200.įor your convenience the topology and all scripts will be available on GitHub Repository VIRL is cheap and provide us wide range of virtual devices we can choose from for our simulation. Whole simulation is run on Cisco VIRL installed as VMWare VM and is using included ASAv and lxc-sshd images. It’s direct result of lack of support for virtual contexts so remember about it as well.Before we start using Cisco ASA REST API let’s get familiar with network topology that will be used in chapters. This mode is not supported so we have to stick to Active-Standby model. We also need to remember we can’t configure Active-Active failover. If we use any other interface the configuration will be accepted but failover never established.įailover lan interface Fail-link GigabitEthernet0/8įailover link State-link GigabitEthernet0/7įailover interface ip Fail-link 192.168.255.253 255.255.255.252 standby 192.168.255.254įailover interface ip State-link 192.168.254.253 255.255.255.252 standby 192.168.254.254įailover ipsec pre-shared-key 0 FailoverKey In this image we must configure failover link using interfaces GigabitEthernet0/8. That means all restrictions applies also to virtual firewall if you run it on VIRL. This is same image that you use in production on ESXi.
Configuration he made was correct except he forgot about one thing – interfaces numbers are important when you setup failover using ASAv.Ĭisco VIRL uses ASAv image for virtual firewalls. I think my configuration is correct, nodes can ping each other but I still cannot establish failover relationship”. I believe that failover is supported configuration on VIRL.
CISCO ASAV REST API MANUAL
I’ve looked through manual and VIRL forum for the solution. One reader asked me few days ago following question when he had problem establishing the failover in his lab: “I’ve tried to create ASA failover pair on VIRL and it was not working.
