One, address description

1,R1--R5 all want a loopback0=10.10.x.x

2, R1--R3 E0 address =1.1.123.x

3, the R2--r4 WAN interface is 1.1.234.X/24

4,r4-r5 WAN Interface =1.1.45.x/24

Two, bridging

Configuring the R1-R3 Ethernet Address

Configuring the physical IP between R2-R4

The frame-relay between R2-R4 is fully interconnected 1

R2:

int S2/2

Frame-relay Map IP 1.1.234.4 204

Frame-relay Map IP 1.1.234.3 203

R3:

int S2/2

Fram Map IP 1.1.123.2 302

Fram Map IP 1.1.123.4 304

R4:

int S2/2

Fame Map IP 1.1.123.2 402

Fame Map IP 1.1.123.3 403

Configure R4-R5 between PPP and configure the appropriate IP

Configuring the R1-R5 Loopback0

Test connectivity

Third, RIP configuration

Speed up RIP Convergence

Router RIP

Times Basic 5 10 10 10

-R1 R3 Ethernet Interface runs RIP v2

-R1 R3 Just send routing updates to each other, and all updates are detail routed

Note: Unicast update routes, support subnets

R1:router RIP

No auto

NET 1.0.0.0

Neighbor 1.1.123.3

R3:router RIP

No auto

NET 1.0.0.0

Nei 1.1.123.1

-The most secure way to validate is to verify that the R3 can accept R1 routes, and R1 does not accept R3 routes

R1:

Key Chani Test

Key 1

Key-string Cisco

int f0/0

IP RIP auten mode MD5

IP RIP authen key-chain test

Sho IP ro

R3:

Ken Chani Test

Key 2

Key-string Cisco

Sho IP ro

RIP MD5 Verification principle: Key-id from the top to the next match, if the other side of the key file and their own does not match, it key-id+1 until the same password, if the other side sent a key-id than their first key-id big, directly Look for and the other Key-id the same, if there is a match, no failure

Solutions 2

Passive one end update detail route, side not update route, receive only

Solutions 3

R1:

Router RIP

IP RIP receive version 1

Four, OSPF basic configuration

-R1-R2 to be able to shorten the convergence time of OSPF and not to conduct elections

Sho IP OSPF neigh view

-the network segment between R4-R5 needs to be elected, and all OSPF packet interactions are unicast

int S2/1

IP OSPF network non-broadcast

Router OS 1

Neighbor 1.1.45.5

-The 234 segment between R2-R4 cannot use the default network type, cannot use the broadcast network type, wants to use the same network type, and can interact with each other through multicast protocol packets

R2:

int S2/2

IP OS net Po-to-mul

R3:

int S2/2

IP OS net Po-to-mul

R4:

int S2/2

IP OS net Po-to-mul

-R1-R5 loopback0 can be placed in any area, but declaring R4 interface into OSPF requires minimal command

R4:

Router OS 1

NET 1.1.45.4 0.0.0.0 a 0

NET 0.0.0.0 255.255.255.255 a 1
