VOIP Lab 2 – VOIP Network Setup

The purpose of this lab is to setup the IP network connectivity configuration between Ballplayers, Inc’s locations in Baltimore and New York to support the eventual VOIP, as depicted in Lab 1.

Tasks 2.1 – Initial IP Network Setup

1. Configure the IP addressing based on the diagram in VoIP Lab 1.
2. R7 will serve as the “hub” location; its WAN interfaces shall have a “.1” host addresses and the corresponding WAN interfaces on the Baltimore and New York WAN interfaces shall have a “.2” host address.
3. Provide a loopback interface on each router using a /32 mask.
4. Configure PPP Encapsulation on the WAN links.
5. Configure the clocking on the R7 with clock rate 128000.
6. Configure OSPF Area 0 for the WAN.
7. Place the R7 loopback in Area 0; the Baltimore loopback in OSPF Area 1; the New York loopback in Area 2.
8. Verify IP connectivity via show ip route and by pinging each interface from each router.

Tasks 2.2 – Verifying the Network Setup

Verifying IP connectivity from Baltimore:

Baltimore#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route

That was fairly easy and straight-forward – CCNP 201 BSCI I guess? Next task I’ll configure the FXS interfaces for the analog phones and some basic VoIP between Baltimore and New York.
