Cisco IOS router practice lab
This is an ISR4321 style IOS XE CLI for CCNA and CCNP routing practice. It is not a real router. The starter config has OSPF process 1 in area 0, BGP in AS 65001, NAT overload, and a sample ACL. Loopback0 is 1.1.1.1 and that address is the router ID.
Show commands on the page include show ip route, show ip route ospf, show ip ospf neighbor, show ip bgp summary, and show ip protocols. Use them to prove which protocol owns a prefix before you add another network statement. Config mode is the usual enable then conf t path.
Guest mode needs no router and no licence. Neighbors in the show output are dummy. You cannot form a real OSPF or BGP adjacency from this page. show ip protocols lists the networks OSPF and BGP are advertising in this config. Compare that with show ip route before you decide a prefix is missing. Sign-in is optional.
Common questions
What routing is already on the box?
OSPF process 1 area 0, BGP AS 65001, NAT overload, a sample ACL, and Loopback0 1.1.1.1 as the router ID.
How do I see only OSPF routes?
show ip route ospf. The full table is show ip route.
Will this peer with my home router?
No. OSPF neighbors and BGP sessions in the output are dummy data.
Where is the router ID?
Loopback0, 1.1.1.1, in the starter config.
ISR4321 with OSPF process 1 (area 0), BGP AS 65001, NAT overload, sample ACL. Loopback0 = 1.1.1.1 router-id. CCNA/CCNP routing practice.
