more frame switch…

another gem from gns3vault…

fram-sw-multi

looks harmless enough… fact is you have to make both point to point and multipoint subs on 2 different networks, and route the frame switch too… you may see something like this in a lab…

frsw#sh frame route

Serial0/0       112             Serial0/1       211             active

and here’s r1:

frame switch…

what a pain in the ass… been about a year since i built one… sometimes there’s just too much bgp…

frameswitch

here’s a template…

r3fr#sh run

!
interface Serial1/0
no ip address
encapsulation frame-relay IETF
clockrate 64000
frame-relay lmi-type cisco

frame-relay route 301 interface Serial1/1 103

encapsulation frame-relay IETF
clockrate 64000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 201 interface Serial1/1 102

then set up the interfaces on the various routers…

gns3vault ccie lab1 basic setup and configs…

rene_ccie_lab1

the below zip contains all the device configs and topology.net…  the dlci’s for the routers have not been set up  but the interfaces are assigned properly to the frame switch, and the switches have only vlan 1… the aim of this is basic point to point connectivity between ip addresses where possible, and cdp, and to save set up time for me later for practice… the first thing you should do is verify always, but you knew that… have fun, or something…

configs

the routers are 3725’s, the switches are 3640’s with esw16-nm
