E120 and E320 System Maximums

Appendix A: System Maximums
Routing Protocol Maximums
Table 11 lists routing protocol maximums for the E120 router and the E320 router. The
following notes are referred to in Table 11:
1.
The total set of FTEs can be shared by interfaces, next hops, ECMP sets, VRs, and
VRFs. Next-hop FTEs identify the next hop on multiaccess media, such as ATM
multipoint, Ethernet, or bridged Ethernet. Each VR or VRF consumes three entries.
Each interface, next hop, and ECMP set consumes a single entry. One FTE is
reserved for internal use, and the system software limits the number of FTEs used
by interfaces to a maximum of 32,000. The remaining FTEs can be shared across
the other types.
2.
On the E120 router, the SRP-120 and the SRP-320 support a maximum of 64,000
IP network interfaces. On the E320 router, the SRP-320 supports a maximum of
96,000 IP network interfaces. The SRP-100 supports a maximum of 64,000 IP
network interfaces.
You can use either all dynamic interfaces or a combination of dynamic and static
interfaces to achieve this maximum.
3.
These values are subject to limitations on available SRP module memory, which
varies according to your router configuration.
4.
Depending on your configuration, the router may support more routing table
entries or fewer routing table entries than this value. In any case, you can choose to
limit the number of routes that can be added to the routing table on a per-VR or
per-VRF basis by means of the maximum routes command.
5.
The maximum number of ANCP adjacencies can be scaled over a maximum of 100
virtual routers. Fewer ANCP adjacencies can be scaled in configurations with more
than 100 virtual routers.
6.
On the E320 router, you can achieve 32,767 total Martini circuits only over Ethernet
interfaces. For all routers, the total Martini circuits can be any combination of
external inter-router circuits and internal circuits (local cross-connects).
7.
There is no per-VR limit; all multicast routes can be on a single VR or present
across multiple VRs.
8.
The maximum number of interfaces can be achieved by any combination; for
example, two streams each being replicated to 32,768 interfaces; 16,384 streams
each being replicated four times; or any other combination.
