1).配置underlay網絡實現互聯互通網絡
2).啓用vxlan功能dom
3).配置業務接入點分佈式
4).啓用E***功能ide
5).配置BGP對等體oop
6).配置E***實例測試
7).配置頭端複製列表ui
8).配置***實例spa
9).配置VBDIF並綁定***實例,配置發佈路由類型router
10).配置BGP對等體路由類型
這次環境以下:
ensp 版本1.3.00.100
ce12800 版本V200R005C10SPC607B607
virtualbox 版本5.1.26
配置拓撲圖以下:
2.配置CE1-CE3使用OSPF實現三層互聯互通:
CE1:
[ce1]ospf 1 router-id 1.1.1.1 \\配置OSPF進程1
[ce1-ospf-1]area 0
[ce1-ospf-1-area-0.0.0.0]quit
[ce1-ospf-1]quit
[ce1]interface g1/0/0
[ce1-ge1/0/0]undo shutdown
[ce1-ge1/0/0]undo portswitch
[ce1-ge1/0/0]ip address 192.168.12.1 255.255.255.0
[ce1-ge1/0/0]ospf enable 1 area 0 \\端口加入OSPF進程
[ce1-ge1/0/0]interface loopback 0
[ce1-loopback1]ip address 1.1.1.1 255.255.255.255
[ce1-loopback1]ospf enable 1 area 0
[ce1-loopback1]interface g1/0/1
[ce1-ge1/0/1]undo shutdown
[ce1-ge1/0/1]undo portswitch
[ce1-ge1/0/1]ip address 192.168.13.1 255.255.255.255
[ce1-ge1/0/1]ospf enable 1 area 0
[ce1-ge1/0/1]quit
[ce1]commit
CE2:
[ce2]ospf 1 router-id 2.2.2.2
[ce2-ospf-1]area 0
[ce2-ospf-1-area-0.0.0.0]quit
[ce2-ospf-1]quit
[ce2]interface g1/0/0
[ce2-ge1/0/0]undo shutdown
[ce2-ge1/0/0]undo portswitch
[ce2-ge1/0/0]ip address 192.168.12.2 255.255.255.0
[ce2-ge1/0/0]ospf enable 1 area 0
[ce2-ge1/0/0]interface loopback 0
[ce2-loopback1]ip address 2.2.2.2 255.255.255.255
[ce2-loopback1]ospf enable 1 area 0
[ce2-loopback1]quit
[ce2]commit
CE3:
[ce3]ospf 1 router-id 3.3.3.3
[ce3-ospf-1]area 0
[ce3-ospf-1-area-0.0.0.0]quit
[ce3-ospf-1]quit
[ce3]interface g1/0/0
[ce3-ge1/0/0]undo shutdown
[ce3-ge1/0/0]undo portswitch
[ce3-ge1/0/0]ip address 192.168.13.3 255.255.255.0
[ce3-ge1/0/0]ospf enable 1 area 0
[ce3-ge1/0/0]interface loopback 0
[ce3-loopback1]ip address 3.3.3.3 255.255.255.255
[ce3-loopback1]ospf enable 1 area 0
[ce3-loopback1]quit
[ce3]commit
配置注意點:
1)注意交換機端口默認狀態爲shutdown,須要手動undo shutdown
ce3上ospf狀態查看
3.配置vxlan隧道模式,並使能vxlan的acl擴展功能
ip tunnel mode vxlan \\配置隧道模式爲vxlan
assign forward nvo3 acl extend enable \\使能vxlan的ACL擴展功能,以防ACL疊加失敗
配置注意點:
此處模擬器不支持配置命令,實際環境仍是要配置的,配置命令後交換機須要重啓。
4.配置LSW1 LSW2接入交換機vlan、trunk
lsw1:
[lsw1]vlan 10
[lsw1-vlan10]quit
[lsw1]vlan 20
[lsw1-vlan20]quit
[lsw1]interface e0/0/2
[lsw1-ethernet0/0/2]port link-type access
[lsw1-ethernet0/0/2]port default vlan 10
[lsw1-ethernet0/0/2]interface e0/0/3
[lsw1-ethernet0/0/3]port link-type access
[lsw1-ethernet0/0/3]port default vlan 20
[lsw1-ethernet0/0/3]interface e0/0/1
[lsw1-ethernet0/0/1]port link-type trunk
[lsw1-ethernet0/0/1]port trunk allow-pass vlan all
lsw2:
[lsw2]vlan 20
[lsw2-vlan20]quit
[lsw2]interface e0/0/2
[lsw2-ethernet0/0/2]port link-type access
[lsw2-ethernet0/0/2]port default vlan 20
[lsw2-ethernet0/0/2]interface e0/0/1
[lsw2-ethernet0/0/1]port link-type trunk
[lsw2-ethernet0/0/1]port trunk allow-pass vlan all
5.配置vxlan業務接入點,配置PC1 PC2 PC3所連交換機端口vxlan功能

[ce2-ge1/0/1]interface g1/0/1.1 mode l2
[ce2-ge1/0/1.1]encapsulation dot1q vid 10 \\配置封裝vlan10
[ce2-ge1/0/1.1]bridge-domain 10 \\關聯BD域
[ce2-ge1/0/1.1]interface g1/0/1.2 mode l2
[ce2-ge1/0/1.2]encapsulation dot1q vid 20 \\配置封裝vlan20

2)PC3連通性測試
3)CE2上查看主機路由信息
3)CE3上查看主機路由信息
