Phi-4多模态推理模型：架构解析与应用实践

配置思路：
一、R1、R2、R3上配置ospf，将除192.168.1.0/24和172.16.1.0/24的路由做通
二、R1、R3上配置IBGP邻居，将192.168.1.0/24和172.16.1.0/24通告进BGP
完成后由于R2上没有192.168.1.0/24和172.16.1.0/24的路由，所以产生路由黑洞
三、R1、R2、R3上配置MPLS LDP
四、静态路由和BGP路由默认不进隧道，R1、R3上通过命令开启进隧道：route recursive-lookup tunnel
| R1 | R2 | R3 |
# interface LoopBack0 route recursive-lookup tunnel | # mpls lsr-id 2.2.2.2 mpls # mpls ldp # # interface GigabitEthernet0/0/0 ip address 10.1.12.2 255.255.255.0 mpls mpls ldp # interface GigabitEthernet0/0/1 ip address 10.1.23.2 255.255.255.0 mpls mpls ldp # interface LoopBack0 ip address 2.2.2.2 255.255.255.255 # ospf 1 router-id 2.2.2.2 area 0.0.0.0 network 2.2.2.2 0.0.0.0 network 10.1.23.2 0.0.0.0 network 10.1.12.2 0.0.0.0 # | # mpls lsr-id 3.3.3.3 mpls lsp-trigger all # mpls ldp # interface GigabitEthernet0/0/1 ip address 10.1.23.3 255.255.255.0 mpls mpls ldp # interface GigabitEthernet0/0/2 ip address 172.16.1.1 255.255.255.0 # interface LoopBack0 ip address 3.3.3.3 255.255.255.255 # bgp 123 peer 1.1.1.1 as-number 123 peer 1.1.1.1 connect-interface LoopBack0 # ipv4-family unicast network 172.16.1.0 255.255.255.0 # ospf 1 router-id 3.3.3.3 area 0.0.0.0 network 3.3.3.3 0.0.0.0 network 10.1.23.3 0.0.0.0 # route recursive-lookup tunnel # |
开启进隧道前：
开启进隧道后：
数据进入隧道，实现互通，解决路由黑洞问题
