Lab 170 - MultiProtocol BGP

Prerequisites: CCNP level skills.

Note!
This topology layout is based on the new physical topology presented here.

In previous lab (Lab 168) I have configured basic L3 reachability (point-to-point) as well as OSPF configuration in the core of the network (R1, R2, R3, SW3).


Topology

Pic. 1 - MPLS Topology.

Task 1
Enable Multiprotocol BGP on all PE routers.

Topology

Pic. 1 - MPLS Topology.

Task 1
Configure standard protocol used in MPLS networks on all PE and P routers. Make sure that PE routers do NOT run tagging protocol on their interfaces facing the customers.

Solution

Lab 168 - Creating MPLS Topology

Prerequisites: CCNP level skills.

Note!
This topology layout is based on the new physical topology presented here.

Topology

Task 1
Using the physical topology presented here configure the IP addressing according to the following diagram. Make sure that all routers and switches can ping each other on a point-to-point basis (All loopbacks use 10.0.x.x/24 addresses where x=router number, sw1=7, sw2=8 etc.).

Task 2
Once devices can ping each other on a point-to-point basis, enable OSPF on links between R1, R2, R3 and SW3 (core of our MPLS network) Advertise loopback addresses as /32 prefixes. Use AREA 0.

New Topology Diagram

After a looong hiatus regarding my blog updates I come back with new set of mini labs and new topology.

Please, watch the video introduction to get familiar with some changes in the blog.

My Dynamips (Dynagen) LAN connections look like shown below:

Pic. 1 - LAN Connections.

WAN links in my labs look as shown in the pic. 2:

Pic. 2 - WAN Connections.

If you use dynamips+dynagen on Linux (like myself) you might find the following topology file useful (keep in mind I start TWO instances of the dynamips hypervisor to off load the CPU).
