Dynamic Routing Protocols Flashcards
What are dynamic routing protocols in Junos OS?
Dynamic routing protocols automatically discover and maintain routes by exchanging routing information between routers, adjusting to network changes.
Name some common dynamic routing protocols used in Junos OS.
Common dynamic routing protocols include OSPF, BGP, and RIP.
How do dynamic routing protocols benefit a network?
They automatically adjust to network changes, provide fault tolerance, and scale well for large networks by sharing routing information.
How is a dynamic routing protocol configured in Junos OS?
A dynamic routing protocol is configured under the “protocols” hierarchy in Junos OS, such as set protocols ospf or set protocols bgp.
What command is used to view the status of dynamic routing protocols in Junos OS?
The command show protocols provides information about the status of dynamic routing protocols like OSPF and BGP.
What is the role of a routing protocol’s “autonomous system” number in dynamic routing?
The autonomous system (AS) number uniquely identifies a routing domain for protocols like BGP, which helps in routing between different networks.
What happens if there are conflicting routes between dynamic routing protocols?
When multiple dynamic routing protocols provide conflicting routes, the router uses route preference, administrative distance, or metrics to determine the preferred route.
What are the key differences between RIP, OSPF, and BGP?
RIP is distance-vector, OSPF is link-state, and BGP is a path-vector protocol. OSPF and BGP are more scalable and suitable for larger networks compared to RIP.
How does a dynamic routing protocol handle changes in network topology?
Dynamic protocols automatically recalculate routes and update the routing table when there are changes in network topology, such as link failures or new network additions.
Can dynamic routing protocols and static routing work together in Junos OS?
Yes, dynamic and static routes can coexist in Junos OS, with static routes typically taking precedence if both exist for the same destination.
