2. Accommodating Conditions and Support Status
2.1 Accommodating conditions
This section describes the conditions that are specifically related to VRF in the manual (AX6700S·AX6300S
Software Manual Configuration Guide Vol.1, 3.2 Device Capacities).
The other required conditions are regarded as common to any VRF.
(1) Number of table entries (common to the AX6700S, AX6600S, and AX6300S series)
The number of table entries for each route is shown in the tables in the manual. Please take careful note of the
following when using VRF:
-The maximum number of entries when using VRF is the sum of the entries in all VRF instances.
-A route is added per VRF instance when using the loopback interface in the VRF instance.
-A route is added per VRF instance when using RIPv2 in the VRF instance.
-Two routes are added per VRF instance when using OSPF in the VRF instance.
-A route is consumed as device-specific information per VRF instance, if using VRF.
(29) Resources for unicast routing (common to the AX6700S, AX6600S, and AX6300S series)
When using OSPF with VRF, the maximum number of neighboring routers for a device is 200. In addition, make
sure that the product of the number of LSAs retained by each VRF instance and the number of neighboring
routers for each VRF instance does not exceed 200,000.
When using OSPFv3 with VRF, the maximum number of neighboring routers for a device is 100. In addition,
make sure that the product of the sum of LSAs retained by all VRF instances and the number of neighboring
routers for all VRF instances does not exceed 100,000.
(30) IPv4 multicast
When using IPv4 multicast for multiple VRF instances, the sum of the global network and VRF instances should
not exceed the values specified by the accommodating conditions below.
