Can EIGRP and OSPF work together?
Note that you can configure and enable two routing protocols on a router (e.g both OSPF and EIGRP). However, this is not enough to exchange information between the two routing protocols. You must configure Redistribution as well.
What if you have a company that is running OSPF and you want another network is running EIGRP or RIP?
What if you have a company that is running OSPF and you just bought another company and their network is running EIGRP? It’s possible that we have multiple routing protocols on our network and we’ll need some method to exchange routing information between the different protocols. This is called redistribution.
Why OSPF is preferred over EIGRP?
EIGRP (Distance vector) like RIP has the ability to turn off the auto-summary feature which advertizes networks at their classfull boundary by default. OSPF does not advertize networks at their classfull boundary, nor does it have the ability to turn this feature on.
Why is OSPF preferred over EIGRP in many companies?
OSPF is used widely because of its strong standard protocol and supporting various manufacturers’ devices. EIGRP is made by the leading network hardware manufacturer, Cisco, so that it occupies much of the market.
Do you need a default route for OSPF?
The OSPF router does not create a default route into the OSPF domain by default. The ‘default-information originate’ command is required for OSPF to generate a default route.
How redistribute default route from OSPF to BGP?
If the default route is not available on the routing table , you can directly add the default route(0.0. 0.0/0) in the redistribution profile of the protocols in the BGP-Network–BGP—Redistribution profile, Network–OSPF–Exportrule and enable the Allow redistribute default route tab and distribute the route.
What is the main difference between OSPF and EIGRP?
EIGRP is a proprietary gateway protocol that contains optimisations intended to minimise routing instability incurred after topology changes; OSPF is a dynamic routing protocol that is used specifically for the IP networks. 2. EIGRP collects data in three tables; OSPF routes IP packets within a single routing domain.
What is the difference between OSPF and EIGRP?
How redistribute OSPF default route into BGP?
The OSPF default route is a metric-type 2….Couple of options:
- Use the network 0.0. 0.0 under the BGP process. Note: 0.0.0.0 must be in the routing table.
- Default-information originate. Same as note as above..
- Default-Originate on the neighbor. With this approach, you don’t need a 0.0. 0.0 in the routing table.
