is allocated towards IP ECMP.

Description
Note:
The configure>system>resource-profile>router context is supported on the 7210 SAS-T,
7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE: standalone, and 7210 SAS-Sx 10/100GE.
The configure>system>global-res-profile>router context is supported on the 7210 SAS-R6,
7210 SAS-R12, and 7210 SAS-Sx/S 1/10GE: standalone-VC.
This command configures the number of directly connected IP interfaces and subnets (both IPv4 and IPv6)
the user plans to use on the node, so that only the requisite number of entries in the L3 forwarding table
are allocated. On the 7210 SAS platforms, the hardware L3 forwarding table (that is, the IP IFB) stores the
IP routes (both IPv4 and IPv6) received from routing peers and also stores the IP address prefix for the
directly connected interfaces. The rest are available for use by IP routes received from peers.
This command provides the flexibility to earmark resources based on the number of directly connected
interfaces required on the node, allowing the user to decrease the number of resources for directly
connected subnets and consequently increase the number of entries available for IP routes received from
peers. See the description of the max-ipv6-routes command for more information about IP route allocation.
Note:
• Each IPv4 subnet configured on the node requires 1 entry and each IPv6 subnet configured
on the node requires 2 entries. Each IPv6 /64-bit address prefix requires twice the amount of
