VRF Design Guide Create the VRF To create the vrf, you need a name and an rd (route distinguisher). The rd is a number which helps to identify the vrf’s routes and allows for overlapping ip address space. It comprises of 2 fields generally represented by an AS number and another arbitrary number (ie 40:40). The vrf must be created on each layer3 hop as it is not propagated throughout the network (must be added on all 4900’s that participate in ospf) router(config)#ip vrf vpn1 router(config#)rd

WHITE PAPER BIDIRECTIONAL FORWARDING DETECTION FOR OSPF Fast Failure Detection to Speed Network Convergence OVERVIEW In both Enterprise and Service Provider networks, the convergence of business-critical applications onto a common IP infrastructure is becoming more common. Given the criticality of the data, these networks are typically constructed with a high degree of redundancy. While such redundancy is desirable, its effectiveness is dependant upon the ability of individual network devices

Kelly Keys NT2640 Fri. Night Project Paper 1. Routing tables and how the router will perform a route lookup: a. Routing Table Format- A routing table is used by TCP/IP network routers to calculate the destinations of messages it is responsible for forwarding. The table is a small in-memory database managed by the router's built-in hardware and software. Each IP address identifies a remote router (or other network gateway) that the local router is configured to recognize. For each IP address
