Zorluk: ZorFloating Static Routes

Complete the Cisco IOS command below to configure a floating static route for destination network 10.40.15.0/2410.40.15.0/24 using next-hop IP address 192.168.254.2192.168.254.2 to serve as a backup for a primary route learned via Internal EIGRP (Administrative Distance 90), specifying an administrative distance of 130130.

Cevap:Router(config)# ip route 10.40.15.0 255.255.255.0 【192.168.254.2】 【130】

Cevap

The completed Cisco IOS configuration command is `ip route 10.40.15.0 255.255.255.0 192.168.254.2 130`.
In Cisco IOS, the syntax for a static route is `ip route <prefix> <mask> <next-hop-ip> [administrative_distance]`. Specifying `192.168.254.2` as the next-hop IP address and appending `130` configures a floating static route. Because 130 is higher than Internal EIGRP's administrative distance of 90, the router keeps this static route inactive in the routing table until the primary EIGRP route is removed.

Adım Adım Çözüm

1
Identify the target network prefix and network mask.
The target prefix is 10.40.15.010.40.15.0 and the subnet mask for /24/24 is 255.255.255.0255.255.255.0.
Cisco IOS static route syntax requires the destination network prefix followed by its subnet mask.
2
Identify the next-hop IP address.
The next-hop IP address for the first blank is 192.168.254.2192.168.254.2.
Traffic destined for 10.40.15.0/2410.40.15.0/24 over the backup link will be forwarded to this next-hop IP.
3
Determine the administrative distance value to make the static route floating.
The administrative distance for the second blank is 130130.
An administrative distance value greater than the primary routing protocol's AD (Internal EIGRP AD = 90) ensures the static route remains floating (inactive in the routing table) until the primary route fails.
