Routing
processor IPv6 unicast
module (RP) path entry count
memory
32MB or more 25,000 or less
96MB or more 25,000 or less
Remarks
(Note 1) Memory must be extended for all RPs implemented in a router.
(Note 2) Memory must be extended so that only the corresponding RP can obtain the minimum required memory.
(The memory required differs for each RP.)
(Note 3) For the accommodation conditions on the number of VCs, see Table 4-63.
4.2.12.4 Number of NDP Entries
In a network of Ethernet and gigabit Ethernet, the hardware address corresponding
to the destination address of a packet to be transmitted is determined by address
solution in NDP. Therefore, the maximum number of destination routers is
determined by the number of NDP entries. The number of NDP entries is shown in
Table 4-63.
