BRANCH Routers Configure WLAN as Station and Connect to HUB Router SSID. Create Bridge and Add EOIP Tunnel and LAN Port to the Bridge. Configure EOIP Tunnels to each Branch Routers. Use Case : Bridging 元MTU 1500, no change to underlying link MTU, fragmentation happens 元MTU 1500, change underlying link MTU, no fragmentation Use Case : Routing can set lower MTU to avoid EoIP GRE packets fragmentation 1500-IP-Ethernet-GRE=1458ġ1 11 LAB SETUP HUB Router Configure WLAN as AP Mode, SSID, Security Profiles. Automatically adds IPsec Peer with Pre-shared key and Policy with default-values (by default phase2 uses sha1/aes128cbc)ĩ 9 IPsec Secret For Encryted EOIP Trafficġ0 10 MTU Factor Consideration Total MTU of EOIP 1542 bytes MTU bytes EOIP Header ((8byte GRE + 14 byte Ethernet + 20 byte IP). Need to specify both local address and remote address of Tunnel. Optionally, IPsec Secret can be added for encrypting EOIP Traffic.
Solutions for L2 Loop STP(Spanning Tree Protocol) RSTP (Rapid Spanning Tree Protocol)Ĩ 8 How To Secure EOIP Tunnel By default, there is no Encryption.
Can cause Layer 2 Loop Broadcast Domain, Unicast Flooding, MAC Table Instability.etc. Head Quarter s Requirement Internet Line Public IP Branch Office s Requirement Internet Line Public IP EOIP Solution which can bridge office LANs across internet.Ħ 6 Case Scenario of Bridging Multiple Office LANsħ 7 Pros and Cons Pros Office LANs can be in same subnet by bridging EOIP and LAN. Can be run over PPTP or IPIP Tunnel or any connections which is able to transport IP.ĥ 5 Why do we use EOIP? Case Scenario Bridging the LANs of the Offices where are located in different Countries. Tunnel MAC address Range : 00:00:5E:80:00:00-00:00:5E:FF:FF:FF IPsec for encryption as optional. Configurable as Layer 2 VPN or Layer 3 VPN L2VPN: All sites in same subnet 元VPN: Each Site is in separate subnet.
