How do I advertise a network in EIGRP?
However, EIGRP also can be configured to advertise networks with a mask different from the default. This is helpful in route summarization and in fixing problems with discontiguous networks. To advertise a different mask, a wildcard mask can be added to the EIGRP network statements.
How do I advertise a default route in EIGRP?
Configure EIGRP in AS 100 on both routers and advertise their directly connected networks. Configure R1 to inject a default route into the EIGRP routing domain. One way to inject a default route into EIGRP is to configure a static default route pointing to Null0 and then redistribute the default route into EIGRP.
How EIGRP chooses the best path through the network?
EIGRP chooses the route through Router Three as the best path, and uses the metric through Router Three as the feasible distance. Since the reported distance to this network through Router Four is less than the feasible distance, Router One considers the path through Router Four a feasible successor.
What EIGRP command do we use to advertise a manually configured static default route to neighbors?
Static Default Route We configure the default route on R2 with FastEthernet 0/1 as the exit interface. In EIGRP we can use the network 0.0. 0.0 command to advertise this.
How do I advertise a default route?
There are two ways to advertise a default route into a normal area. The first is to advertise 0.0. 0.0 into the OSPF domain, provided the advertising router already has a default route. The second is to advertise 0.0.
How to get rid of EIGRP route advertisements?
The solution to this problem is either to configure a distribute list that prevents the router from advertising all those static routes or to change the static routes to reference the next-hop IP addresses instead of an interface. This way, the router will not advertise all these static routes and flood the entire network with unnecessary routes.
What does EIGRP stand for in network advertising?
EIGRP is advertising routes with a metric that is not understood by the network administrators. This section discusses methods for troubleshooting issues related to EIGRP not advertising routes to the neighbors.
How do I exchange EIGRP routes with another router?
In order for two routers to exchange EIGRP routes, they must both be part of the same subnet and have a “network” command specifying that particular subnet, or, at the very least, their specific IP address on that subnet. Confused? That’s OK, I’ll explain it in more detail soon.
How does the EIGRP metric affect route selection?
The EIGRP metric is the basis of route selection done by EIGRP, which selects the route with the lowest EIGRP metric to the destination network. An unexpected EIGRP metric being sent or received on the router might alter route selection to the destination network. The end result might be suboptimal routing.
