Appendix A. ISDN Switch Types, Codes, and Values

Part II

Section X: BGP Configuration

1. R2, and R7 are in autonomous system 2001. R5 is in autonomous system 5, and R4 is in autonomous system 4. Configure an IBGP peer from R2 to R7. Also configure an EBGP from R2 to R5 and from R7 to R4.

2. On R4, assign and advertise the loopback network 220.128.1.0/24 through BGP. On R5, assign and advertise the loopback network 24.128.1.0/24, 24.128.2.0/24 through BGP.

3. Have R5 advertise a default route to the ATM network if ”and only if ”it has the route 220.128.1.0/24.

4. Configure R4 so that all routes from AS 2001 have a weight of 350.

Section XI: DLSw Configuration

1. Configure a DLSw TCP peer from R1, VLAN 1 to R2, VLAN 20. On VLAN 20, there is an SNA host with the MAC address of 2200.900e.0001. Allow only explorer frames destined toward this address to cross the DLSw peer.

2. Configure a DLSw TCP peer between R4, Ring 2, and R1, VLAN 1.

3. Allow the peer on R4 to stay "connected," even upon a loss of the Frame Service. It might take up to three minutes for the network to converge over the ISDN link. The peer should not become disconnected during this time.

Section XII: Miscellaneous Cisco IOS Software Features

1. Transparently bridge from VLAN 30 to VLAN 1, across the Frame Relay cloud.

2. Configure R1 as an NTP server. Configure a peer association so that R4 synchronizes to R1. When R4 is synchronized, allow R2 and R3 to synchronize off R4. If R4 is not synchronized with R1, R2 and R3 should not synchronize.

3. Bridge and route IPX on VLAN 30.
