The following IP parameters have been added in this Solaris release:
The following TCP parameters are new in this Solaris release:
The following TCP/IP parameters are obsolete in this Solaris release.
ipc_tcp_conn_hash_size
tcp_compression_enabled
tcp_conn_hash_size
ip_forwarding
ip6_forwarding
xxx_forwarding
In this Solaris release, IP forwarding is enabled or disabled by using the routeadm command or the ifconfig commands instead of setting the following tunable parameters with the ndd command:
ip_forwarding
ip6_forwarding
xxx_forwarding
Using the routeadm command and the ifconfig command instead of the ndd command to set IP forwarding provides the following advantages:
All settings are persistent across reboots
The new ifconfig router and -router commands can be placed in the /etc/hostname.interface files, along with other ifconfig commands that are run when the interface is initially configured.
To enable IPv4 or IPv6 packet forwarding on all interfaces of a system, you would use the following commands:
# routeadm -e ipv4-forwarding |
# routeadm -e ipv6-forwarding |
To disable IPv4 or IPv6 packet forwarding on all interfaces of a system, you would use the following commands:
# routeadm -d ipv4-forwarding |
# routeadm -d ipv6-forwarding |
In previous Solaris releases, you would enable IPv4 or IPv6 packet forwarding on all interfaces of a system as follows:
# ndd -set /dev/ip ip_forwarding 1 |
# ndd -set /dev/ip ip6_forwarding 1 |
In previous Solaris releases, you would disable IPv4 or IPv6 packet forwarding on all interfaces of a system as follows:
# ndd -set /dev/ip ip_forwarding 0 |
# ndd -set /dev/ip ip6_forwarding 0 |
If you want to enable IP forwarding on a specific IPv4 interface or IPv6 interface, you would use syntax similar to the following for your interface. The bge0 interface is used an as example.
# ifconfig bge0 router |
# ifconfig bge0 inet6 router |
If you want to disable IP forwarding on a specific IPv4 interface or IPv6 interface, you would use syntax similar to the following for your interface. The bge0 interface is used an as example.
# ifconfig bge0 -router |
# ifconfig bge0 inet6 -router |
Previously, IP forwarding was enabled on a specific interface as follows:
# ndd -set /dev/ip bge0:ip_forwarding 1 |
# ndd -set /dev/ip bge0:ip_forwarding 1 |
Previously, IP forwarding on a specific interface was disabled as follows:
# ndd -set /dev/ip ip_forwarding 0 |
# ndd -set /dev/ip ip6_forwarding 0 |
If you want any of the preceding routeadm settings to take effect on the running system, use the following command:
# routeadm -u |
