One physical interface can have more than one dialer with different configuration, which mean one physical BRI can make and receive more than one call. But in this lab example we'll only simulate one dialer for one physical interface. HQ username Branch password cisco dialer-list 1 protocol ip permit isdn switch-type basic-ni Most of the setting will be issued on dialer interface, on physical BRI interface only SPID HQ BRI interface interface Bri0  no ip address  no ip directed-broadcast  isdn spid1 32177820010100 //only SPID configure here, no ip address and tel num  dialer pool-member 1 //reference to the dialer interface, can belong to multiple dialer pool  encapsulation ppp  ppp authentication chap HQ dialer interface interface Dialer1  ip address 100.11.1.1 255.255.255.0  encapsulation ppp  dialer pool 1    //define the pool group number  dialer remote-name branch //remote site to dial  d...

1.Configure interesting traffic, dialer-list and authentication for remote router on HQ configure command as below isdn switch-type basic-ni username branch password cisco   //specify username and password for remote router dialer-list 1 protocol ip permit   //permit all ip traffic for dialer group number 1 issue the same command for Branch router username HQ password cisco dialer-list 1 protocol ip permit isdn switch-type basic-ni 2.Configuring the BRI interface to dial on demand HQ interface Bri0  ip address 100.11.1.1 255.255.255.0  no ip directed-broadcast  dialer-group 1  //dialer list 1 was defined above  isdn spid1 32177820010100  dialer map ip 100.11.1.2 name branch broadcast 7782001  //number to call when match the ip address  encapsulation ppp  ppp authentication chap Branch interface Bri0  ip address 100.11.1.2 255.255.255.0  no ip directed-broadcast  dialer-group 1  isdn spid1 32177820020100 ...

Network Diagram In this lab, we'll learn how to control redistribution base on the tag. Setup your network as topology, addressing and routing protocol above. Make sure everything working correctly. Create route-map and set tag using ACL. filter the traffic we want to control using ACL, in this case we gonna create an ACL group of classless network coming from router C, done on router B ip access-list standard CLASSLESS  permit 10.1.1.4 0.0.0.3  permit 6.0.0.0 0.15.255.255  permit 146.6.0.0 0.0.15.255  permit 206.6.6.0 0.0.0.15 create a route-map and set the specific tags route-map SET_TAGS permit 10  match ip address CLASSLESS  set tag 1 ! route-map SET_TAGS permit 20  set tag 2 //we didn't set ant match, anything don't match ant from above will fall under this group now apply this route-map to be redistribute into OSPF 1 router ospf 1  log-adjacency-changes  redistribute eigrp 1 subnets route-map SET_TAGS ...

Network Diagram Redistribute network from EIGRP to OSPF using route-map. we have 9 network, 10.11.1.x - 10.11.9.x to redistribute from EIGRP to OSPF we'll divided or filter this into 3 group using access-list. ip access-list standard NET1to3  permit 10.11.1.0 0.0.0.255  permit 10.11.2.0 0.0.0.255  permit 10.11.3.0 0.0.0.255 ip access-list standard NET4to6  permit 10.11.4.0 0.0.0.255  permit 10.11.5.0 0.0.0.255  permit 10.11.6.0 0.0.0.255 ip access-list standard NET7  permit 10.11.7.0 0.0.0.255 once we done with the grouping, now let's define the route-map, their match group and the specific charataristic. We'll assume that acl group NET4to6 more important than NET1to3, so we'll set this group with lower metric, both also will be converted into different type of OSPF external network. Third route-map will deny ip address matches the ACL NET7 from being redistribute. route-map RM1 permit 10  match ip address NET1to3...

for this lab, we gonna use same topology and setup from previous lab  Redistribution RIP Ver2 - OSPF 1. First we gonna stop route to 172.16.2.x and 172.16.3.x to be advertised into R2 on R1 create access-list to match the two address ip access-list standard ROUTE_FILTER  deny   172.16.3.0 0.0.0.255  deny   172.16.4.0 0.0.0.255  permit any //don't forget this, by default access-list deny all then apply inside the routing protocol on specific interface, in this case, go to RIP and apply on the R1 interface serial 0/0 router rip  version 2  network 10.0.0.0  network 172.16.0.0  distribute-list ROUTE_FILTER out Serial0/0  no auto-summary now check on R2, R3 and R4, you should see no route to this two network 2. Now we gonna apply distribution list where the filter is applied between routing protocol, here we gonna filter network 172.16.1.x coming from RIP from being advertised into OSPF  on R2, creat...
