How to connect BB1-FRSW-R6?

According to the BASIC BGP configuration,

S0/0 of R6 is:

int s 0/0

no sh

ip add 54.1.1.6 255.255.255.0

encapsulation frame-relay

frame-relay map ip 54.1.1.254  101 broadcast

no shut

.

But its counterpart BB1 has much more DLCI.

Like 100, 201, 301 401.

If R6 has only one DLCI, that is 101, what about the others?

  • Hi castor,

    Hope i'm getting you well, you only need 1 DLCI to connect from BB1 to R6. BB1 connects to R6 using 51, 100, 101 from the addresses 54.1.3.254, 54.1.2.254, 54.1.1.254 respectively. But if you check you FR config, DLCI 101 from R6 goes to DLCI 101 of BB1, and that's all you need to get connectivity as per the INE topology.

    If you are using dynamips, i hope you are starting BB1 too.

    HTH.

  • Castor,

    As swadummy indicated, the backbone router is configured with multiple DLCIs and corresponding IP subnets to provide a variety of ways to connect - some of the Volume II labs use each DLCI and IP subnet, and some use RIP, EIGRP, OSPF or BGP as the routing protocol to provide additional variety. Each lab and diagram shows the DLCI and IP subnet to use.

    According to the BASIC BGP configuration,

    S0/0 of R6 is:

    int s 0/0

    no sh

    ip add 54.1.1.6 255.255.255.0

    encapsulation frame-relay

    frame-relay map ip 54.1.1.254  101 broadcast

    no shut
