All routers will have DLSw configured to replace transparent bridging over the WAN links. The remote routers should be able to see the static address for the mainframe in their reachability tables. Only IP will be used over the WAN links and the ISDN will only come up when the primary link fails. DLSw should not bring up the ISDN link. | vLab Title 3050.

Be able to configure DLSw with an ISDN dial backup link for disaster recovery. Outcomes All routers will have DLSw configured to replace transparent bridging over the WAN links. The remote routers should be able to see the static address for the mainframe in their reachability tables.

Author Mickey Stewart CCIE 3129 John Albritton Lab Vendor MentorLabs LLC Pod Type 3-Router Pod Assignment The Texas Pride Oil company wants to enable DLSw with ISDN dial backup between the headquarters and the oil refineries. Currently the sites are transparently bridged together. Conditions The routers are already configured for IP routing using EIGRP as a routing protocol. When configuring DLSw on the Houston HQ router statically configure a MAC address to simulate an IBM mainframe using an address of . When configuring the remote routers statically configure a MAC addresses to simulate IBM mainframes. Use the address for Austin and the address for SanAntonio. Use the IP addresses of the Ethernet 0 interfaces on the routers for the DLSw peers. All routers have a login password of cisco and an enable password of san-fran. For the ISDN dial up links their are no SPIDs and the switch type is basic-5ess. The phone numbers are 1111 for the Houston router 2222 for the Austin router and 3333 for the SanAntonio router. Use the hostnames of the routers as the PPP usernames. Notes When configuring the dialup link remember to configure PPP authentication. The network is divided up so that floating static routes
