Dear all,
I need to configure a Cisco C1113 (router B) to enable BGP Routing between two networks.
Router A is already configured by my provider and I need to configure my router B, but I would need to make sure that my configuration is correct...
Here is the connexion I established:
ASN 50624 ASN 50600 (vlan2) ______ ______ 10.1.0.10 10.0.0.0 | | 169.254.253.1 | | 10.1.0.11 ---------| A |-----------------------| B |---------- 10.1.0.14 |______| 169.254.253.2 |______| 10.1.0.24 connexion between router A and B is done through a SFP Fiber
I would need to make sure that my 4 IPs from ASN 50600 are available over the network 10.0.0.0...
Here is the configuration I set:
for interfaces:
enable configure terminal interface GigabitEthernet0/1/0 switchport mode access switchport access vlan 2 interface vlan 2 ip address 10.1.0.10 255.255.255.0 description TS1 end configure terminal interface GigabitEthernet0/1/1 switchport mode access switchport access vlan 2 interface vlan 2 ip address 10.1.0.11 255.255.255.0 description TS 2 end configure terminal interface GigabitEthernet0/1/2 switchport mode access switchport access vlan 2 interface vlan 2 ip address 10.1.0.24 255.255.255.0 description H Preprod end configure terminal interface GigabitEthernet0/1/3 switchport mode access switchport access vlan 2 interface vlan 2 ip address 10.1.0.14 255.255.255.0 description H Prod end
and for BGP:
enable configure terminal ip route 10.1.0.0 255.255.255.0 null 0 interface GigabitEthernet0/0/0.2 encapsulation dot1q 2 ip address 169.254.253.2 255.255.255.0 end enable configure terminal router bgp 50600 redistribute connected redistribute static bgp router-id 169.254.253.2 bgp log-neighbor-changes neighbor 169.254.253.1 remote-as 50624 network 10.1.0.0 mask 255.255.255.0 address-family ipv4 unicast redistribute connected neighbor 169.254.253.1 default-originate neighbor 169.254.253.1 advertisement-interval 25 network 10.1.0.0 mask 255.255.255.0 neighbor 169.254.253.1 activate exit-address-family address-family ipv4 multicast redistribute connected neighbor 169.254.253.1 default-originate neighbor 169.254.253.1 advertisement-interval 25 network 10.1.0.0 mask 255.255.255.0 neighbor 169.254.253.1 activate exit-address-family neighbor 192.254.253.1 activate end
As I'm not familiar with BGP Protocol, if you can just help me to make sure that configuration is set correctly ? do I need to perform any additional configuration ?
Many thanks for your help !

Hello
Not sure you need to send a default route or advertise the null static towards your provider, apart from that the bgp configuration looks okay

thanks paul for your confirmation, I'll launch this config in the coming days as I need to be onsite to do it...
