Multicast Routing Protocol on IP appliances - FAQ
Solution

Show All

This article discusses Multicast routing protocols such as DVMRP, PIM-SM, PIM-DM and how to configure them in conjunction with Check Point Security Gateways on IP Appliance Platforms.

Can I run DVMRP (Distance Vector Multicast Routing Protocol) and PIM (Protocol Independent Multicast) at the same time?

Only one multicast routing protocol can be used for multicast packets on the Nokia Appliance.

What changes need to be made to allow Multicast Routing to work with a Check Point Security Gateway?

Use modzap for IPSO 3.x and 4.x to make the following change:

nokia[admin]# modzap _fw_allow_unknown_if $FWDIR/boot/modules/fwmod.o 0x1


(Will change _fw_allow_unknown_if at offset 0xac09c from 0x00000000 to 0x00000001)

Please explain why my Nokia IP Appliance will not route Multicast Packets?

Are Multicast Packets "flowed" by Firewall Flows or SecureXL?

No they are not.

How to prevent multicast packets from being dropped by Check Point Security Gateway anti-spoofing rules?

How does multicast behave in a High-Availability Configuration?

Does VRRP support High Availability Failover for Multicast Traffic?

Why is there temporary suppression of multicast data traffic if a source has been silent for some period of time?

How do I prevent an IPSO platform from becoming the designated router (DR) during the PIM DR election?

Are there any interoperability issues with Cisco Routers using PIM?

What settings do we support for DVMRP (Distance Vector Multicast Routing Protocol)?

What is the meaning of [LOG_WARNING] ipsrd[237]: PIM CRP: no elected bsr to send crp advertisement?

What is the meaning of [LOG_WARNING] ipsrd[205]: dvmrp_recv_prune: duplicate prune from 192.168.1.255 for (239.255.255.49, 192.168)/48, time remaining 900 seconds?
