IKEv1 IPsec Site-to-Site VPN configuration on Cisco ASA 8.4(x)

IPsec Site-to-Site VPN are good alternative to a point-to-point lease lines when cost matters. Our goal is to configure site-to-site or l2l IPsec VPN between ASA1 and ASA2 which are running IOS 8.4(2). IP addressing scheme is mentioned in the network diagram.

Ansible-Playbook to display output of multiple show commands (using stdout_lines with Loop)

 In this playbook, we we'll see how we can get display of multiple show commands in stdout_lines format. We can make use of loops (or with_items) for submitting multiple commands, but debug output with stdout_lines does not gives the formatted result as it would give for single command. So in case of multiple commands, we can debug the output of each command separately in stdout_lines format.

Filtering Routes in BGP using Route-maps and Prefix-list

Image
Order of preference of attributes in BGP The order of preference varies based on whether the attributes are applied for inbound updates or outbound updates. For inbound updates the order of preference is:     route-map     filter-list     prefix-list, distribute-list For outbound updates the order of preference is:     prefix-list, distribute-list     filter-list     route-map NOTE: The attributes prefix-list and distribute-list are mutually exclusive, and only one command (neighbor distribute-list or neighbor prefix-list) can be applied to each inbound or outbound direction for a particular neighbor. Scenario: We own the AS500 and advertising a network block of 192.0.2.0/24 and 180.179.179.0/16 to two different ISPs. Objectives: Configure router R1 to establish eBGP neighbor relationship with ISP1. Configure router R1 to establish eBGP neighbor relationship with ISP2. Advertise  192.0.2.0/24 ...

Ansible Playbook for Network OS Upgrade with pre and post checks

You have 100s of network switches or routers that you need to upgrade. How much time would it take for you to do the upgrades? There are a lot number of sub-tasks involved while upgrading IOS image of a Cisco router or a switch. This time of upgradation can be reduced through automation from various Enterprise Configuration Management tools that also have ability to upgrade network OS. Though these tools give an easy to use graphical interface, but this requires you to have appropriate license and also restricts you to customize your upgrade process.

NSX-T Configuration from Scratch

Image
 In this blog post we'll see step by step configuration of NSX-T 1. Add Compute Manager 2. Create Transport Zones as following      a. One Overlay Transport Zone for Host and Edge Transport Nodes      b. Two VLAN Transport Zones. One for Host Transport Nodes and another for Edge Transport Node. (having two separate VLAN transport zones is not necessary, a single VLAN Transport Zone can be used Host and Edge Transport zones) 3. Create Uplink profile for Host Transport Node      In our design, we are using LAG consisting of two uplink on Host Transport Nodes. LAG is already created on vCenter ESXi hosts. Transport VLAN is the VLAN used for Host TEP IP address pool. There is no need to specify the MTU size in Host Uplink Profile, as we are using converged VDS in our design and MTU settings need to configured in VDS (on vCenter).     MTU Settings on VDS 4. Create IP pool for Host Transport Nodes. In our case, we would be using DHCP...
