How do I redistribute a default route in EIGRP?

How do I redistribute a default route in EIGRP?

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. When redistributing a static, connected, or EIGRP route for another AS, the metric does not need to be assigned. The default route will be an external EIGRP route.

How BGP distribute default route?

How do you redistribute a route in BGP?

  2. redistribute type-1.
  3. redistribute type-2.

How do I advertise a default route in BGP?

To advertise a BGP default route to a BGP neighbor, use the neighbor default-originate router configuration command. For example, when the IP prefix 0.0. 0.0/0 is removed from the BGP table with the no network command and the default route advertisement is configured on EBGP session from PE-A to Site-A …

What is the command for default route?

Use the ip default-gateway command when ip routing is disabled on a Cisco router. Use the ip default-network and ip route 0.0. 0.0 0.0. 0.0 commands to set the gateway of last resort on Cisco routers that have ip routing enabled.

How do I advertise a default route?

How do I redistribute EIGRP to BGP?

In order to mutually redistribute the eBGP routes in to EIGRP, use the redistribute bgp command with EIGRP metrics. Similarly, in order to redistribute EIGRP routes in to BGP, use the redistribute eigrp AS number command.

What is default route configuration?

In computer networking, the default route is a configuration of the Internet Protocol (IP) that establishes a forwarding rule for packets when no specific address of a next-hop host is available from the routing table or other routing mechanisms.

How to check EIGRP routes in router R3?

Shows the default route from router R3. !— EX indicates that the routes are EIGRP external routes. In order to verify that EIGRP routes are redistributed in BGP properly, use the show ip route bgp command in router R3.

Which is the default network topology for EIGRP?

This is the topology we will use: R1 and R2 are configured for EIGRP, R2 is connected to an ISP router. Behind the ISP is network 3.3.3.0 /24 that we can use to test our default route. Nothing special, R1 and R2 are neighbors but that’s it. We configure the default route on R2 with FastEthernet 0/1 as the exit interface.

Can you use the network command in EIGRP?
