E120 and E320 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.
