MPLS VPN lab #3

This lab will test a Central Services MPLS VPN.

The diagram is the same as my last VPN Lab. Also it uses my MPLS topology found over here:

This is the topology for this lab (click for a bigger image):

MPLS2 - small

  • Customer1 and Customer 2 both have MPLS vpn’s through the ISP core.
  • Customer1 is using OSPF and Customer2 is using EIGRP
  • Customers should have no access to each others networks
  • Customers should be able to reach all their sites from all their sites
  • The ISP is now providing a mail relay for it’s customers to use. Ensure that all customers can get to the subnet through their vpn’s, but they must still be seperated from each other.

Checking optical interface type

Sometimes you log onto a switch remotely and need to know what kind of optical interface the switches actually have plugged in. It’s pretty simple:

Switch#show interface gi1/0/25 capabilities
Model:                 WS-C3750G-24TS
Type:                  1000BaseLX SFP
Speed:                 1000
Duplex:                full
Trunk encap. type:     802.1Q,ISL
Trunk mode:            on,off,desirable,nonegotiate
Channel:               yes
Broadcast suppression: percentage(0-100)
Flowcontrol:           rx-(off,on,desired),tx-(none)
Fast Start:            yes
QoS scheduling:        rx-(not configurable on per port basis),
tx-(4q3t) (3t: Two configurable values and one fixed.)
CoS rewrite:           yes
ToS rewrite:           yes
UDLD:                  yes
Inline power:          no
SPAN:                  source/destination
PortSecure:            yes
Dot1x:                 yes

The most important things here is that you can see I have a 1000BaseLX SFP installed.
