IP via triangle routing, where data is tunneled back to the home network before being forwarded to the final destination However, this approach is less efficient than Mobile IPv6 GRE is referred to as Generic Routing Encapsulation, a Cisco-proprietary tunneling protocol It forms (unencrypted) virtual point-to-point links which are able to encapsulate a variety of protocols inside IP packets IPv6 Basic... Below describes the steps when Host1 establishes an SCTP session with Host2: i) Host1 sends an initialization request to Host2 Host1 waits for a message from Host2 ii) Host2 receives the request Host2 generates an encrypted key and a message authentication code (indicates the creator of the message – Host2), and includes these information into a cookie message Host2 sends the cookie message to Host1... and networks to reach the IPv6 Internet over IPv4 networks - IPv4 to IPv6 transition is a slow process, as it requires planning and implementation of new addressing, protocol stacks, and applications Generally, the deployment of IPv6 should start from the network edges, and move towards the network core - There are many transition mechanisms available to smooth the IPv4 to IPv6 transition The most... information: Interior Gateway Protocols (IGPs) Similar to RIPv2 Still has a limit of 15 hops and uses split horizon and RIPng (RIP Next poison reverse to prevent routing loops Uses the all-RIP-routers Generation) multicast group FF02::9 for sending updates to all RIPng routers Updates are sent on UDP port 521 Advertises routes every 30 seconds Similar to EIGRP It includes a new Protocol-Dependent Module... configures an IPv6 address with the last 64 bits of the IPv6 address in EUI-64 format The link-local keyword configures a specific link-local IPv6 address on an interface instead of using the automatically generated Interface ID in EUI-64 format Note: This command does not enable the Neighbor Discovery Protocol - Basic IPv6 addressing configuration on RT1: RT1#conf t Enter configuration commands, one per... msec Prefix 2345:6789:AAAA:3::/64 onlink autoconfig Valid lifetime 2592000, preferred lifetime 604800 PC2# - Network engineers often use easier-to-remember values like ::1 instead of the automatically generated Interface ID in EUI-64 format when assigning link-local and global unicast addresses 31 Copyright © 2010 Yap Chin Hoong www.yapchinhoong.com IPv6 Static Routing and Default Routing Configuration
