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 network to ISP1 only. Advertise 180.179.179.0/16 network to ISP2 only. Receive routes having n

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.

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.

Cisco ASA Active/Active Failover Configuration

Image
Active/Active failover is only available to security appliances in multiple context mode. In an Active/Active failover configuration, both security appliances can pass network traffic. In Active/Active failover, you divide the security contexts on the security appliance into failover groups. A failover group is simply a logical group of one or more security contexts. You can create a maximum of two failover groups on the security appliance. The admin context is always a member of failover group 1. Any unassigned security contexts are also members of failover group 1 by default. We have already seen the configuration for Active/Standby failover in the previous article. This article focuses on how to configure an Active/Active Failover configuration on ASA Security Appliance.

Creating MPLS Layer 3 VPN

Image
When used with MPLS, the VPN feature allows several sites to interconnect transparently through a service provider's network. One service provider network can support several different IP VPNs. Each of these appears to its users as a private network, separate from all other networks. Within a VPN, each site can send IP packets to any other site in the same VPN. Each VPN is associated with one or more VPN routing and forwarding instances (VRFs). A VRF consists of an IP routing table, a derived Cisco express forwarding (CEF) table, and a set of interfaces that use this forwarding table.
