Exercise 4BGP Over SVR


Step 1Configure Routing Interface ( loopback if )
bosdc1

Router: > Routing Instance

ADD Routing Interfaces

name rtg-int-bos   

IP address: 6.6.6.6


show config running authority router bosdc1 routing default-instance interface rtg-int-bos

routing interface 
admin@node1.bosdc1# show config running authority router bosdc1 routing default-instance interface rtg-int-bos 

config

    authority

        router  bosdc1
            name     bosdc1

            routing  default-instance
                type       default-instance

                interface  rtg-int-bos
                    name        rtg-int-bos
                    ip-address  6.6.6.6
                exit
            exit
        exit
    exit
exit

Codes: K - kernel route, C - connected, S - static, R - RIP,
       O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
       T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP,
       F - PBR,
       > - selected route, * - FIB route

C>* 6.6.6.6/32 is directly connected, rtg-int-bos, 00:09:29
seabo1

name rtg-int-sea  

IP address: 7.7.7.7

dalbo2

name rtg-int-dal  

IP address: 8.8.8.8

Step 2Change Router ID to Routing Interface  ( BGP will use  loopback address)

for all the site:

bosdc1

seabo1

dalbo2

Router: > Routing Instance  > BGP

Step 3Add BGP Over SVR Peers  ( Add Neighbors in DC )
bosdc1

Router: > Routing Instance:   > BGP

AD: neighbors

Seattle:

BGP Neighbor Address: 7.7.7.7
Neighbor AS Number: 100

Local Address:  Routing   +    Routing Interface:   rtg-int-bos

Time-to-live Value: 5   ( for BGP Multihop Settings )

Address Families. Select bgp:ipv4-unicast.  (  +   Router As Next Hop: True   )


Dallas:

BGP Neighbor Address: 8.8.8.8
b. Neighbor AS Number: 200

Local Address:  Routing   +    Routing Interface:   rtg-int-bos

Time-to-live Value: 5   ( for BGP Multihop Settings )

Address Families. Select bgp:ipv4-unicast.  (  +   Router As Next Hop: True   )



neighbor

seabo1

BGP Neighbor Address: 6.6.6.6
Neighbor AS Number: 300
Local Address: rtg-int-sea (on Seattle) 

Local Address:  Routing   +    Routing Interface:   rtg-int-sea

Time-to-live Value: 5   ( for BGP Multihop Settings )

Address Families. Select bgp:ipv4-unicast.  (  +   Router As Next Hop: True   )


dalbo2

BGP Neighbor Address: 6.6.6.6
b. Neighbor AS Number: 300
c. Local Address: rtg-int-dal (on Dallas)

Local Address:  Routing   +    Routing Interface:   rtg-int-dal

Time-to-live Value: 5   ( for BGP Multihop Settings )

Address Families. Select bgp:ipv4-unicast.  (  +   Router As Next Hop: True   )


Step 4Add BGP Over SVR Peers  ( Add Neighbors in Branches )
