#EIGRP IP FAST REROUTE VS OSPF IP FAST REROUTE UPDATE#

Routing with EIGRP is done in Neighbour Tables, Topology tables, and Routing tables. OSPF is a connection state protocol, while EIGRP is a distance vector protocol. IGRP does not support areas or tables but supports multi-part routing. EIGRP is a Cisco-only protocol, while OSPF is a generic protocol. Routing with OSPF is done in Autonomous System, Areas, Stub Areas and Backbone areas. In RIP, networks are not divided into areas or tables.

#EIGRP IP FAST REROUTE VS OSPF IP FAST REROUTE UPDATE#

IGRP uses the distance vector algorithm to calculate the best path and the variance mechanism to support unequal-cost load balancing.ĮIGRP uses Diffusing update algorithm to calculate the best path. OSPF uses the SPF algorithm to calculate the best path. RIP uses Distance vector algorithm to calculate the best path The metrics used are bandwidth, delay, load and reliability EIGRP vs OSPF Standard EIGRP although there is an EIGRP RFC 7868, is an Informational RFC. 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. The metrics used are bandwidth, load, delay, MTU, and reliability. EIGRP vs OSPF Fast Reroute OSPF can support Fast Reroute with LFA, Remote LFA, TI-LFA, and RSVP-TE FRR as with EIGRP. The metrics used are bandwidth and delay. IGRP stands for Interior Gateway Routing ProtocolĮIGRP stands for Enhanced Interior Gateway Routing ProtocolĮIGRP Is derived from Integrated Gateway Routing Protocol RIP stands for Routing Information Protocol Difference between RIP, OSPF, IGRP, and EIGRP RIP Here is the side by comparison table of all these routing protocols. These routing protocols use different methods and metrics to route the packets. The value represents the weight of the Adj-SID for the purpose of load balancing.Routing protocols include Routing Information Protocol (RIP), Open Shortest Path First (OSPF), Interior Gateway Routing Protocol (IGRP), and Enhanced Interior Gateway Routing Protocols (EIGRP). Other bits: MUST be zero when originated and ignored when received. An autonomous system is a group of networks and network equipment under a common administration. When set, the P-Flag indicates that the Adj-SID is persistently allocated, i.e., the Adj-SID value remains consistent across router restart and/or interface flap. OSPF (Open Shortest Path First) is an interior gateway protocol (IGP) that is used within large autonomous systems (ASs). When set, the S-Flag indicates that the Adj-SID refers to a set of adjacencies (and therefore MAY be assigned to other adjacencies as well). If set, then the value/index carried by the Adj-SID has local significance. If set, then the Adj-SID carries a value. If set, the Adj-SID is eligible for protection (e.g., using IP Fast Reroute (IPFRR) or MPLS Fast Reroute (MPLS-FRR)). If set, then the Adj-SID is used when forwarding IPv6-encapsulated traffic to the neighbor.ī-Flag: Backup Flag.

If unset, then the Adj-SID is used when forwarding IPv4-encapsulated traffic to the neighbor. By default, the flag is UNSET.į-Flag: Address-Family Flag. If set, then the Prefix-SID carries a value (instead of an index). If set, any upstream neighbor of the Prefix-SID originator MUST replace the Prefix-SID with a Prefix-SID that has an Explicit NULL value (0 for IPv4 and 2 for IPv6) before forwarding the packet. The zebra daemon then, alters the linux IP networking information on the host. If set, then the penultimate hop MUST NOT pop the Prefix-SID before delivering the packet to the node that advertised the Prefix-SID.Į-Flag: Explicit NULL Flag. All routing daemons communicate directly to zebra daemon. OSPF is an Interior Gateway Protocol (IGP), where routers connect networks using the Internet Protocol (IP). This is a classless routing protocol which also assists variable-length subnet masking (VLSM) and discontiguos networks. P-Flag: No-PHP (No Penultimate Hop-Popping) Flag. OSPF (Open Shortest Path first) This can be used and deployed in a variety of networks. The N-Flag is set when the Prefix-SID is a Node-SID If set, then the Prefix-SID refers to the router identified by the prefix.Typically, the N-Flag is set on Prefix-SIDs that are attached to a router loopback address. If set, then the prefix to which this Prefix-SID is attached has been propagated by the router from either another level (i.e., from Level-1 to Level-2 or the opposite) or redistribution (e.g., from another
