What is the maximum hop count for a RIP route?

RIPv1 and RIPv2

Which versions of RIP are used for IPv4?

RIPng (RIP Next Generation)

Which version of RIP is used for IPv6?

Request and Response

What are the two message types used in RIP?

RIPv1

What version of RIP only advertises classful addresses?

RIPv1

Which version of RIP doesn’t support VLSM and CIDR?

RIPv2

Which version of RIP supports VLSM and CIDR?

RIPv1

Which version of RIP sends messages using broadcast?

RIPv2

Which version of RIP sends messages using multicast?

224.0.0.9

What address are RIPv2 messages multicast to?

router rip

Enter RIP configuration mode:

R1(config)#[…]

version 2

Enable RIPv2:

R1(config-router)#[…]

no auto-summary

Disable RIP auto summarization:

R1(config-router)#[…]

network [ip-address]

Enable RIP on all interfaces in the specified range:

R1(config-router)#[…]

passive-interface [interface-id]

Configure the router to stop sending RIP advertisements out of a RIP-enabled interface:

R1(config-router)#[…]

default-information originate

Configure a RIP-enabled router to advertise its default route to its RIP neighbors:

R1(config-router)#[…]

224.0.0.10

What address are EIGRP messages multicast to?

No

Can RIP perform unequal-cost load-balancing?

Yes

Can EIGRP perform unequal-cost load-balancing?

No

Can OSPF perform unequal-cost load-balancing?

distance [value]

Modify RIP’s AD on the local router:

R1(config-router)#[…]

maximum-paths [number]

Modify the number of paths RIP will perform ECMP load-balancing over:

R1(config-router)#[…]

router eigrp [as-number]

Enter EIGRP configuration mode:

R1(config)#[…]

no auto-summary

Disable EIGRP auto summarization:

R1(config-router)#[…]

Yes

Does the EIGRP AS number have to match between EIGRP neighbors?

passive-interface [interface-id]

Prevent the router from sending EIGRP messages out of an EIGRP-enabled interface:

R1(config-router)#[…]

network [ip-address] [wildcard-mast]

Enable EIGRP on interfaces in the specified range:

R1(config-router)#[…]

1. Manual Configuration

2. Highest IP address on a loopback interface

3. Highest IP address on a physical interface

What is the EIGRP Router ID selection priority?

eigrp router-id [a.b.c.d]

Configure the EIGRP router ID:

R1(config-router)#[…]

Feasible Distance

EIGRP: The metric value from the current router to the route’s destination

Reported Distance (aka Advertised Distance)

EIGRP: The neighbor’s metric value to the route’s destination

Successor

EIGRP: The route with the lowest metric to the destination (the best route)

Feasible Successor

EIGRP: An alternate route to the destination which meats the feasibility condition. Reported distance is lower than the successor router’s feasible distance.

feasible successor

EIGRP will only perform unequal-cost load-balancing over […] routes
