Verify pings from R3 – R5 8.0 Configure X.25 for the connection from R1 to R2 9.0 Configure async routing between the auxillary ports on R1 and R4 Cisco Systems Internal Use Only 5 SE Practice CCIE Lab V1.4 Configure Routing Protocols per the Routing Topology Diagram 10.0 Configure OSPF as shown in the diagram 11.0 Setup Area 3 as a Stubby Area and configure OSPF MD5 authentication throughout area 1 12.0 Configure IGRP as shown in the diagram. Redistribute these routes with other routing protocols to allow full network connectivity 13.0 Configure EIGRP as shown in the diagram. Redistribute these routes with other routing protocols to allow full network connectivity 14.0 Configure R5 and R2 to be IBGP neighbors 14.1 Configure R2 and R4 to be IBGP neighbors 14.2 Do not configure peering statements between R5 and R4 14.3 Configure BGP on R5, R4 and R2 with an AS of 5 14.4 Configure R5 such that it will pass routes to an EBGP neighbor (ISP) 129.45.80.73/30 AS 254 14.5 Make sure that the only external BGP route that is accepted by R5 is that of the network 192.78.5.0 14.6 Configure BGP supernetting using ip address 129.45.0.0. This is to be advertised to AS 254 only. Make sure that there are no update problems with this route being advertised back into your IGP and IBGP. Verify that all BGP speakers can see the proper BGP routes 15.0 Ensure that routing advertisements for all protocols are only being sent out on the interfaces noted in the diagram. Ensure that the best path is taken as the limits of your routing protocols allow. Remember NO static or default routing of any kind 16.0 At this point you should be able to ping from any interface to nearly any other interface throughout the ENTIRE network 16.1 Verify network connectivity Configure Fault Tolerance 17.0 Configure ISDN using these numbers: 17.1 Port1 SPID1 0835866101 DN 835-8661 (Router 3) 17.2 Port1 SPID2 0835866301 DN 835-8663 17.3 Port2 SPID1 0835866201 DN 835-8662 (Router 5) 17.4 Port2 SPID2 0835866401 DN 835-8664 17.5 Switch type is NI1 18.0 R5 should be set up as the dialer when its serial link goes down 18.1 Use ISDN as a backup link, when the frame-relay connection to R3 is lost 18.2 Use CHAP authentication 19.0 Configure fault tolerance between R2 and R4’s Ethernet. Make sure that no packets from the Ethernet network are lost when the frame-relay links on either Cisco Systems Internal Use Only 6 SE Practice CCIE Lab V1.4 of the routers goes down IP Firewall 20.0 Allow the partner subnet 192.64.5.0 access to R5’s s1 network via R4 only 20.1 Make sure all other subnets access R5’s s1 via R2 21.0 Configure an outbound access list on R5’s Serial1 Interface 21.1 Permit FTP originating from R1’s Token Ring network 21.2 Deny TFTP anywhere 21.3 Allow smtp, www, and ping from anywhere Network Address Translation 22.0 Configure NAT on R5’s ethernet interface 22.1 Host addresses are 1.1.1.1 to 1.1.1.30 22.2 Use the valid network on R5’s ethernet interface as the outside addresses Network Time Protocol 23.0 Configure authenticated NTP on all routers 23.1 Make R2 the authoritative NTP server 23.2 Only allow R3 to synchronize with the time on R2 the master timeserver 23.3 Configure R2s clock to represent the correct time Desktop Protocols 24.0 Enable IPX RIP on all LAN segments 25.0 Enable IPX EIGRP on the frame-relay, ISDN and x.25 network connections 26.0 Configure 2 static SAPs on R4’s Token Ring 27.0 Filter SAP on R4’s E0 such that it will only advertise 1 SAP 28.0 Verify that these 2 SAPs appear in R2’s SAP table 29.0 Configure IPX route filtering such that R3 will not see IPX routes from R5 30.0 Configure LAT between R3 and R5 30.1 Verify that you can establish LAT sessions between R3 and R5 30.2 Ensure that the connections made are always LAT and never telnet 31.0 Enable AppleTalk RTMP on all LAN segments 32.0 AppleTalk EIGRP on all possible WAN segments besides ISDN. 33.0 Configure tunnels in the Frame Relay Network Cisco Systems Internal Use Only 7 SE Practice CCIE Lab V1.4 33.1 Make sure that the tunnel for the connection between R3 and R5 uses no AppleTalk cable ranges, while the other connections do. 34.0 Filter AppleTalk zones on R4 such that users on the token ring will only sees its own zone. DLSW+ 35.0 Configure DLSW+ on R4’s token ring and R1’s and R3s ethernet interfaces 36.0 Configure R4 as a DLSW+ Border Peer to both R2 and R3 36.1 Use TCP for the connection between R3 and R4 36.2 Use FST for the connection between R2 and R4 37.0 Allow only SNA from R3 to R1 and R4 38.0 Allow only Netbios between R1 and R4 39.0 Setup filters such that the Token Ring announces only the Mac address of the FEP.
