我需要配置 Cisco C1113(路由器 B)以启用两个网络之间的 BGP 路由。

我配置了我的路由器 B,但我需要确保我的配置是正确的......

这是我建立的连接:

         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

我需要确保我的 4 个来自 ASN 50600 的 IP 在网络 10.0.0.0 上可用...

这是我设置的配置:

对于接口:

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

对于 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

由于我对 BGP 协议不熟悉,您是否可以帮助我确保配置设置正确?

配置为 switchport 的接口没有 IP 地址。虚拟接口 (VLAN 2) 有一个 IP 地址,该地址用作 VLAN 上主机的默认网关。
