[python]Automating OSPF configuration of two routers

Network diagram There are two vIOS which are R1 and R2, they have their gi0/2 and gi0/3 connected to the R5 switch, the configuration is pushed from the cloud through their gi0/2 and gi0/3 to configure their gi0/0 to become OSPF neighbours. Objective To configure the two routers to become ospf neighbors, the OSPF configuration … Continue reading [python]Automating OSPF configuration of two routers

Extending the python script to configure OSPF with ncclient

Previously I have successfully download the configuration from the netconf enabled router, now i have extended support to configure ospf. This is a simple lab to further extend and get myself familiarize and comfortable with netconf. During the lab I was careless, I inadvertently left a space on my netconf snippet that breaks my script … Continue reading Extending the python script to configure OSPF with ncclient

OSPF virtual link with message digest authentication

Dis-contiguous area Non-backbone area has to be converged with backbone area (area 0) in order for OSPF to learn the routes. The following example has area 100 discontiguous with backbone area, the solution is either to use GRE tunnel or virtual link. Virtual link 1. Router-id is used for virtual-link neighbor not the IP address … Continue reading OSPF virtual link with message digest authentication

Palo Alto Networks: OSPF and L3 Link aggregation

The previous post about Cisco VSS is to integrate with Palo Alto Firewalls. Layer 3 link aggregation on PA firewall Click on Network tab and select Interfaces from the menu on the left. There is an "Add Aggregate Group" at the bottom of the page, it may seem quite unnoticeable. After the link aggregation link … Continue reading Palo Alto Networks: OSPF and L3 Link aggregation

BGP: Injecting IGP route into BGP without redistribution

The diagram is complicated with an additional link, and instead of full BGP route in AS65000, the BGP route is propagated with the help of OSPF. In previous lab, the BGP full mesh was established by peering both subnets of a BGP router. However this step can be simplified by peering the BGP speaker's loopback … Continue reading BGP: Injecting IGP route into BGP without redistribution
