Now that everything is configured, I check the routing tables from routers on both networks to confirm that the redistribution worked and all routes are learned below, I confirm this using routers R1 and R4. Also, the “default metric 100 10 255 1 1500” command used when redistributing into EIGRP sets the bandwidth to 100 Kbps, delay to 10 tens-of-microseconds, reliability to 255, and an MTU of 1500 bytes.

OSPF, however, involves a small time to install a new route and re-route traffic once a failure occurs. Topology The example topology consist of six XRv routers with IP. When a network becomes unreachable from the best path, EIGRP can fall directly to the alternate best path. EIGRP: The Hybrid Protocol EIGRP stands for Enhanced Interior Gateway Routing Protocol, and it is a proprietary routing protocol developed by Cisco. By default OSPF will only redistribute classfull routes this command is needed so subnets within the classfull range will be redistributed. EIGRP’s DUAL algorithm maintains a loop-free alternative path. This technology is able to recover impacted.

BGP Peer Groups BGP Neighbor Adjacency States BGP Messages How to read the BGP Table How to advertise networks in BGP BGP Auto-Summary 3.7.b: iBGP and eBGP. IP Fast Reroute (IPFRR) is resiliency technology to provide fast traffic recovery upon link or node failure for mission critical services. Introduction to BGP 3.7a: Neighbor Adjacency. Notice the “redistribute eigrp 1 subnets” command on R3’s configuration. OSPF Loop-Free Alternate (LFA) Fast Reroute (FRR) OSPF Remote Loop-Free Alternate (LFA) Fast Reroute (FRR) 3.7: BGP. Take a look at R3’s configuration this is where all the action is. we also change OSPF timers to have fast IGP convergence, this is the configuration we use based on Cisco recommendations: router ospf ispf nsf ietf mpls ldp sync timers throttle lsa all 0 20 5000 timers throttle spf 50 50 5000 timers lsa arrival 15 timers pacing flood 15 mpls ldp igp sync holddown 60000 hope this helps.

This makes EIGRP lightning fast in the event of a failure of a route. However, it also has some disadvantages, such as being vendor-specific, and having potential issues with scalability and compatibility.Below is the configuration I used. EIGRP (Enhanced Interior Gateway Routing Protocol) belongs to the class of distance-vector protocols. Open Shortest Path First (OSPF) and Enhanced Interior Gateway Protocol (EIGRP) are. EIGRP has some advantages, such as being flexible, efficient, and reliable, and supporting unequal-cost load balancing and route summarization. EIGRP routers also maintain a topology table, which contains information about all the possible paths to each destination, and a routing table, which contains the best path to each destination. EIGRP routers form neighbor relationships with their peers, and exchange routing updates only when there is a change in the network topology. It considers multiple factors, such as bandwidth, delay, load, and reliability, as the metrics to select the best path, and uses a formula called the composite metric to calculate the path cost.
a link-state routing protocol - OSPF RFC2328 RFC2740 RFC5340 or. EIGRP can converge faster if there is a Feasible Successor compared to OSPF but both of them can support IP FRR - Fast Reroute as well. It uses a hybrid algorithm, which combines the features of both distance-vector and link-state protocols. RFC 5286 IP Fast Reroute: Loop-Free Alternates September 2008 Table of Contents 1. EIGRP stands for Enhanced Interior Gateway Routing Protocol, and it is a proprietary routing protocol developed by Cisco.
