Dynamic Ip Routing (Rip And Rip2); Proxy Address Resolution Protocol (Proxy Arp); Point-To-Point Protocol (Ppp); Point-To-Point (Ppp) Connectivity Enhancements - New With V5R1 - IBM i series Handbook

Dynamic IP Routing (RIP and RIP2)

Routing Information Protocol (RIP) is a dynamic IP routing protocol that communicates with
adjacent routers, informing each other of their respective network connections. Dynamic
routing protocols make network maintenance easier and improves network performance and
reliability. iSeries includes both RIP version 1 and RIP version 2. Version 2 of RIP adds
security and efficiency features.

Proxy Address Resolution Protocol (Proxy ARP)

Proxy ARP is an IP networking technique that allows one machine, the proxy agent, to
answer ARP request on behalf of another machine. It is useful for SLIP, PPP, and twinax
connections. This is because it can make devices appear to be all logically on the same local
LAN subnet and, therefore, avoid the need to implement either dynamic routing protocols or
static route definition.

Point-to-Point Protocol (PPP)

Point-to-Point Protocol (PPP) is an open protocol for wide area network TCP/IP connectivity
that can support both dial and leased lines. It can be used to extend an enterprise intranet
across multiple locations. It is also the defacto standard for connecting to the Internet through
an Internet Service Provider (ISP). PPP is a more robust alternative to SLIP (Serial Line
Internet Protocol), when used as a dial-up protocol. PPP's IDSN support enables iSeries to
attach to ISDN switched networks. Using PPP, the iSeries provides an excellent integrated
solution for remote LAN access and as a remote office gateway into an organization's
intranet.
Point-to-Point (PPP) Connectivity Enhancements – New with V5R1
Operations Navigator enhancements improve the ease of use when configuring and
managing Point-to-Point connectivity. Significant enhancements in function and the GUI
capabilities improve the iSeries Point-to-Point connectivity.
• Multi-link allows multiple PPP links to be grouped together to form a single virtual link
or bundle. The links that make up the bundle must be the same type. For example, all
L2TP lines, all PPP analog leased, all PPP ISDN switched, etc. If a switched line
connection is utilized, the PPP connection could be configured to use multiple links for
one connection.
• MP requires that MP support is implemented on both ends of a PPP link. MP can be
implemented with both Originator and Receiver Connection Profiles. The benefits of
MP include:
– Reducing the latency of data sent between systems by increasing the total effective
bandwidth.
