Extreme - Load Sharing, OSPF

## 대역폭 확대와 로드 밸런싱을 위한 Load Sharing 사용 (=Cisco Ether Channel)

## 좌우 EXOSwitch-1,2 // 라우터 역할을 수행하는 EXOSwitch-Router를 두었음. (이중화는 다음에)

## OSPF 프로토콜 사용하여 Routing Table 확인

## Hostname 변경 ##

EXOSwitch-Router]

config snmp sysName EXOSwitch-Router

EXOSwitch-1]

config snmp sysName EXOSwitch-1

EXOSwitch-2]

config snmp sysName EXOSwitch-2

## Load Sharing ##

enable sharing [LAG 그룹의 논리적 마스터 포트] grouping [Group 시작 포트 - Group 마지막 포트]

EXOSwitch-Router]

enable sharing 3 grouping 3-4

show port sharing

 

EXOSwitch-1]

enable sharing 3 grouping 3-4

show port sharing

 

EXOSwitch-2]

enable sharing 5 grouping 5-6

show port sharing

## VLAN_172, VLAN_192 설정 및 Tagging ##

## VLAN 생성 (VLAN_172, VLAN_192)

EXOSwitch-Router]

config vlan Default delete ports all

 

create vlan VLAN_172

config vlan VLAN_172 ipaddress 172.16.10.254/24

config vlan VLAN_172 tag 10

 

create vlan VLAN_192

config vlan VLAN_192 ipaddress 192.168.20.254/24

config vlan VLAN_192 tag 20

EXOSwitch-1]

config vlan Default delete ports all

 

create vlan VLAN_172

config vlan VLAN_172 ipaddress 172.16.10.251/24

config vlan VLAN_172 tag 10

 

create vlan VLAN_192

config vlan VLAN_192 ipaddress 192.168.20.251/24

config vlan VLAN_192 tag 20

EXOSwitch-2]

config vlan Default delete ports all

 

create vlan VLAN_172

config vlan VLAN_172 ipaddress 172.16.10.252/24

config vlan VLAN_172 tag 10

 

create vlan VLAN_192

config vlan VLAN_192 ipaddress 192.168.20.252/24

config vlan VLAN_192 tag 20

## Tagged, Untagged

EXOSwitch-Router-1]

config vlan VLAN_172 add port 3 untagged

config vlan VLAN_192 add port 5 untagged

3-4, 5,6 포트가 Load Sharing 되어 있어, 마스터 포트에만 VLAN을 할당해주면 Sharing Group에 자동으로 할당된다.

show port no-refresh

 

EXOSwitch-1]

config vlan VLAN_172 add ports 1, 3 untagged

show port no-refresh

 

 

EXOSwitch-Router-2]

config vlan VLAN_192 add port 2, 5 untagged

show port no-refresh

## PC IP 설정

PC1]

ip 172.16.10.1 255.255.255.0 172.16.10.251

show ip

 

PC2]

ip 192.168.20.2 255.255.255.0 192.168.20.252

show ip

## OSPF 돌릴기 전 Ping Test

PC1]

ping 172.16.10.251

ping 172.16.10.254

Router까지 핑이 제대로 나가는 것을 확인

 

PC2]

ping 192.168.20.252

ping 192.168.20.254

Router까지 핑이 제대로 나가는 것을 확인

## OSPF ##

## OSPF를 돌리기 위해서 Ipforwarding을 Enable 시켜줘야 함.

EXOSwitch-Router, EXOSwitch-1, EXOSwitch-2]

enable ipforwarding vlan VLAN_172

enable ipforwarding vlan VLAN_192

EOXSwitch-Router]

config ospf routerid 1.1.1.1
config ospf add vlan VLAN_172 area 0.0.0.0
config ospf add vlan VLAN_192 area 0.0.0.0
enable ospf

 

EXOSwitch-1]

config ospf routerid 2.2.2.2
config ospf add vlan VLAN_172 area 0.0.0.0
config ospf add vlan VLAN_192 area 0.0.0.0
enable ospf

 

EXOSwitch-2]

config ospf routerid 3.3.3.3
config ospf add vlan VLAN_172 area 0.0.0.0
config ospf add vlan VLAN_192 area 0.0.0.0
enable ospf

## OSPF 정보 확인

EXOSwitch-Router]

show ospf neighbor

EXOSwitch-1]

show ospf neighbor

EXOSwitch-2]

show ospf neighbor

## OSPF 적용 후 Ping Test ##

PC1]

ping 192.168.20.2

 

PC2]

ping 172.16.10.1
