P-660R-F1 Support Notes

multicast groups. The latest version is version 2 (see RFC2236). IP hosts use

IGMP to report their multicast group membership to any immediate-neighbor

multicast routers so the multicast routers can decide if a multicast packet needs

to be forwarded. At start up, the P-660R-F1 queries all directly connected

networks to gather group membership.

After that, the P-660R-F1 updates the information by periodic queries. The

P-660R-F1 implementation of IGMP is also compatible with version 1. The

multicast setting can be turned on or off on Ethernet and remote nodes.

P-660R-F1 supports IGMP v1 and v2 without source filtering.

 IP Multicast Setup

(1) Enable IGMP in P-660R-F1's LAN in Web Configurator, Advanced Setup,

Network -> LAN -> IP -> Advanced Setup.

(2) Enable IGMP in P-660R-F1's remote node in Web Configurator, Advanced

Setup, Network -> WAN ->Internet Connection -> Advanced Setup.

Key Settings:

Multicast

IGMP-v1 for IGMP version 1, IGMP-v2 for IGMP version 2.

13. Using Zero-Configuration

 Zero-Configuration and VC auto-hunting

Zero-Configure feature can help customer to reduce the burden of setting efforts.

Whenever system ADSL links up system will send out some probing patterns,

system will analyze the packets returned from ISP, and decide which services the

ISP may provide. Because ADSL is based on a ATM network, so system have to

pre-configured a VPI/VCI hunting pool before Auto-Configure function

begins to work.

The Zero-Configuration feature can hunt the encapsulation and VPI/VCI value,

and system will automatically configure itself if the hunting result is successfully.

This feature has two constraints:

1. It supports the ISP provides one kind of service (PPPoE/PPPoA, etc.) only,

otherwise the hunting will get confusing and failed.

2. VC auto-hunting only supports dynamic WAN IP address. If the router is set

a static WAN IP address. VC auto-hunting function will be disabled.

The entry of hunting pool must also contain the VPI, VCI, and which kinds of

hunting patterns you wish to send. Whenever system send out all the probing

patterns with specific VPI/VCI, system will wait for 5~10 seconds and get the

response from ISP, the response patterns will decide which kinds of ADSL

services of the line will be. After that, system will save back the correct VPI, VCI

and also services (encapsulation) type into profile of WAN interface.
