HQ LAN will use OSPF area 1. Once the configuration is done, other branch routers should be able to reach HQ LAN. hq-rtra# router ospf 1  log-adjacency-changes   network 10.1.1.0 0.0.0.255 area 1  network 10.9.9.1 0.0.0.0 area 0  network 70.0.0.1 0.0.0.0 area 0 hq-core01#sh run | be router router ospf 1  log-adjacency-changes  network 10.1.1.0 0.0.0.255 area 1  network 10.1.3.98 0.0.0.0 area 1  network 10.1.11.0 0.0.0.255 area 1  network 10.1.12.0 0.0.0.255 area 1  network 10.1.13.0 0.0.0.255 area 1  network 10.1.14.0 0.0.0.255 area 1  network 10.1.15.0 0.0.0.255 area 1 hq-core02#sh run | be router router ospf 1  log-adjacency-changes  network 10.1.1.0 0.0.0.255 area 1  network 10.1.11.0 0.0.0.255 area 1  network 10.1.12.0 0.0.0.255 area 1  network 10.1.13.0 0.0.0.255 area 1  network 10.1.14.0 0.0.0.255 area 1  network 10.1.15.0 0.0.0.255 area 1 hq-inet# router o...

sooo.. before we proceed to make HQ LAN available over the WAN to other branch, make sure you have below config ready. There'll be a couple of changes from the original plan, I've decided to use Vlan interface rather than Loopback for Core01/02. After all config applied, make sure all point to point are ping-able. Hq-rtra interface Loopback0  ip address 10.9.9.1 255.255.255.255 ! interface FastEthernet0/0  ip address 10.1.1.1 255.255.255.0 interface Serial0/1  ip address 70.0.0.1 255.255.255.0  encapsulation frame-relay  ip ospf network point-to-multipoint  clock rate 2000000  frame-relay map ip 70.0.0.2 102 broadcast  frame-relay map ip 70.0.0.3 103 broadcast  no frame-relay inverse-arp router ospf 1  log-adjacency-changes  network 10.9.9.1 0.0.0.0 area 0  network 70.0.0.1 0.0.0.0 area 0 Hq-rtrb interface FastEthernet0/0  ip address 10.1.2.1 255.255.255.0 Hq...

We could use a few type of frame-relay network (NBMA or point-to-multipoint). Let's go with point-to-multipoint, it's like a collection of point-to-point network from each sites. This is not going to be a Hub and Spokes network because each site have it's own DLCI to others. So it's a full mesh network. Add below command on all WAN interfaces to make a point-to-multipoint Frame-relay network. interface Serial0/1  ip ospf network point-to-multipoint configure OSPF area 0 for the WAN interfaces and Loopbacks, do the same for the rest of the Net router ospf 1  log-adjacency-changes  network 10.9.9.1 0.0.0.0 area 0  network 70.0.0.1 0.0.0.0 area 0 make sure neighbor are formed between the three WAN routers. below are a few useful command to get some information and troubleshoot. show ip route show ip route ospf sh ip ospf interface serial 0/1 show ip protocols show ip ospf show ip ospf neighbor next we will configure routin...

set the DLCI for NetA Frame-Relay switch as below configure the Routers IP as below, make sure they can ping to each other IP address. hq-rtra# interface Serial0/1  ip address 70.0.0.1 255.255.255.0  encapsulation frame-relay  clock rate 2000000  frame-relay map ip 70.0.0.2 102 broadcast  frame-relay map ip 70.0.0.3 103 broadcast  no frame-relay inverse-arp End moon-rtra# interface Serial0/1  ip address 70.0.0.2 255.255.255.0  encapsulation frame-relay  clock rate 2000000  frame-relay map ip 70.0.0.1 201 broadcast  frame-relay map ip 70.0.0.3 203 broadcast  no frame-relay inverse-arp End mars-rtra# interface Serial0/1  ip address 70.0.0.3 255.255.255.0  encapsulation frame-relay  clock rate 2000000  frame-relay map ip 70.0.0.1 301 broadcast  frame-relay map ip 70.0.0.2 302 broadcast  no frame-relay inverse-arp end do the s...

let's start a route lab, I don't really have a specific topic to focus on, but basically we will go thru three main topics related to OSPF, EIGRP and Redistribution (or maybe some others thing that might seems to be a good idea to be included along the way) In this scenario, we have a HQ and two branch office. All three sites connected via 2 ISP (WAN), NetA for primary and NetB for backup. HQ and Moon sites have their own Internet gateway. prepare your GNS topology as below diagram with (1) DLCI (2) GNS3 (3) IP scheme details *please take note that I missed Loopback 0 for all the WAN routers. rtra hq/moon/mars - 10.9.9.1/2/3 255.255.255.255 rtrb hq/moon/mars - 10.9.9.11/12/13 255.255.255.255 next lab we will start with Frame-relay configuration. *please take note that first half of the upcoming labs will focus on Primary WAN which is NetA network, we will bring up the backup WAN later..

please refer to previous post for details and configuration. before we get started, please take notes that we can only filter routes from being installed into the router's routing table, that means we can only filter inbound routes. We'll filter Could 5 (10.10.5.0/24) on R4, so that Cloud 1 & 2 (192.168.1.0 and 192.168.2.0) could not reach Cloud 5. Before changes, Cloud 1/2 can reach Cloud 5 VPCS[1]> ping 10.10.5.1 10.10.5.1 icmp_seq=1 ttl=61 time=32.803 ms 10.10.5.1 icmp_seq=2 ttl=61 time=39.639 ms 10.10.5.1 icmp_seq=3 ttl=61 time=37.984 ms 10.10.5.1 icmp_seq=4 ttl=61 time=37.612 ms 10.10.5.1 icmp_seq=5 ttl=61 time=34.332 ms Create access list for the interested route, and apply it on OSPF process 1 access-list 1 deny   10.10.5.0 0.0.0.255 access-list 1 permit any router ospf 1 ..  distribute-list 1 in FastEthernet0/0 Now Cloud 5 should not be available to Cloud 1 and 2 VPCS[1]> ping 10.10.5.1 *192.168.1.254 icmp_seq=1 ttl=255 ti...
