CCIE Notes

Frame Relay

Read entire Lab before start

Write every thing

Always Note what u do

Do not use the static and default routes just if specified

Use DLCI’s provided

Draw the whole lab

Read instruction carefully

Configure the frame relay portion and only uses the PVC shown in the diagram

See the Frame topology figure first and configure it

Command---- clear frame-relay-inarp

Command---- frame map ip dlci # broadcast

Sub interface interfaces s0/0.23 (where 2 is connected with 3)

Review the frame-relay configurations and commands

64000 clock rate

Command---- show frame-relay map

PVC’s mapping

Write your points.

Redistribute rip subnets metric 1785 metric type 1 tag 5

Always using the Tags for all the ospf core

Check on the very far router with the sh ip route command

External types

Not go to the backbone routers

OSPF

One of the core protocol

Link state IGP

Uses its own transport protocol

IP number 89

Access list 100 permit 89 any any

Access list 100 permit ospf any any

Router ospf [process-id]

Network [address] [wildcard] area [area]

Not relate with subnet originate

Wildcard mask does not relate to subnet mask

Network 0.0.0.0 255.255.255.255 area 0

Network 1.0.0.0 0.255.255.255 area 1

Network 1.1.0.0 0.0.255.255 area 2

Network 1.1.1.0 0.0.0.255 area 3

Network 1.1.1.1 0.0.0.0 area 4

Forming OSPF adjacency:

Must match

Hello / dead timers

MTU

Ip ospf mtu-ignore

Compatible network types

Stub flags

Authentication

Must be unique

Ip address

OSPF router-id

Never uses 1.1.1.1 or like 2.2.2.2 in the lab exam

OSPF network Types

Broadcast

Non-Broadcast

Point to point

Point to multipoint

Point to multipoint non broadcast

DR/ BDR Election

Priority 0 to 255

Higher Priority

0 = never

Designated Router and Backup designated router

Router-id

Highest loop-back / interface IP all 255.255.255.255 and 0.0.0.0

Can be statically set

Higher better

Network type multicast, broadcast & uni-cast

Broadcast and non-broadcast

Backup Designated router become Designated router when DR gone down

In the lab exam remember and work step by step work on later 2 before jumps to layer 3.

Verify before jumps over the other step, work speedy.

Interface command bandwidth

Interface command ip ospf cost

Process auto-cost

Process neighbor a.b.c.d cost

Show ip ospf database

LSA is for DR

Network types

Broadcast & no broadcast works with DR/BDR

P-to-P, P-toMP & P-to-MP non broadcast works with the attributes.

OSPF convergence works with the spf time .

Different types works with the different times.

BGP

Simple redistribution IGP to BGP

Commands:

Router bgp 1

Redistribute ospf

Distribute-list out

Exit

Access-point permit

Commands:

Router bgp 1

Redistribute route-map intobgp

Exit

Router-map into bgp permit

Match ip address

Set origin igp

exit

access-list permit

Route Redistribution

Know how to redistribution works.

When you become the expert you see the network design or diagram you can see what and where we use.

Redistribution Overview

Sh ip route

Which are the advertised protocols.

Routing table only has connected then we make to add the OSPF, RIPs also the connected routes (redistribute RIP subnets).

If any route is not the routing table to any other protocol’s routing table then it’s not working properly.

Note: review the core workbook. CCIE Lab is not the place to learn anything you have to an expert before CCIE Lab.

Router ospf 1

Redistribute rip subnets

?metric, metric-type

?tag

RIP is enabled on our E0/0 and S0/1 interfaces.

Redistribute connected subnets route-map

Route-map permit 10

Match interface E0/0 s0/1

Redistribute ospf 1 metric transparent

Never over configuring the equipment.

Check out the route map also using the deny maps.

Redistribution between 3 processes in one routers
