<Jeremy's IT Lab> Day 25: RIP & EIGRP

RIP & EIGRP

 

RIP:

-> max hop count 15

-> update every 30mins

-> msg type: response / request

   (1) RIPv1 (not use):

      -> only advertise classful adrs(class A, B, C..)

      -> doesn't support VLSM, CIDR (subnet)

      -> msg broad cast   

(2) RIPv2: 

      -> doesn't support VLSM, CIDR (subnet)

      -> msg multi cast (send specific group) <224.0.0.9>

 

EIGRP:

-> advanced ver

-> Cisco only

-> no limitation hop-count

-> msg multi cast <224.0.0.10>

 

network cmd (RIP, EIGRP, OSPF)

-> select int with IP adrs within specific range

-> ativate RIP on those int

-> form adjacent with connect RIP neighbor

-> advertise NW prefix of int

 

Router ID order of priority:

1) manual config

2) highest IP on loopback (virtual int) int

3) highest IP on physical int

 

EIGRP metric

• feasible distance: router's destin (router's metric val)
• reported distance: router's destin (neigbor's metric val)
• successor: lowest destin (best route)
• feasible successor: alter (not best route, bc of loop prevention)

CLI:

default-information originate

#advertise its defualt route

ip route 0.0.0.0 0.0.0.0 0.10.12.1 

#config default route

router eigrp 1

#AS must be match

network 172.16.1.0 0.0.0.15[wild card mask]

#inverted subnet mask (0: must match, 1: don't have to match)
