Physical and Logical Density Maximums

Table 2 lists physical and logical density maximums for the ERX routers. The following notes are referred to in Table 2:

  1. Wire rate indicates the port density that supports maximum (wire-rate) performance. Oversubscribed indicates the port density possible when you are willing to accept less than wire-rate performance by oversubscribing the available fabric bandwidth. The ERX310 and ERX1440 routers do not support oversubscription; port densities for these models indicate wire-rate performance.
  2. When you pair the GE-2 or GE-HDE line module with the GE-2 SFP I/O module on the ERX1440 router, you can terminate up to 24 Gigabit Ethernet interfaces. Slots 2 and 4 on the ERX1440 router support two Gigabit Ethernet interfaces at wire rate; the remaining 10 slots support one Gigabit Ethernet interface at wire rate. On the ERX310 router, all four ports (active and redundant) are at wire rate.
  3. For more information about bandwidth and line-rate considerations for the GE-2 line module or the GE-HDE line module and their corresponding I/O modules on E Series routers, see JunosE Physical Layer Configuration Guide, Chapter 5, Configuring Ethernet Interfaces.

  4. When you pair the GE-HDE line module with the GE-8 I/O module on the ERX1440 router, you can terminate up to 96 Gigabit Ethernet interfaces. Slots 2 and 4 on the ERX1440 router support two Gigabit Ethernet interfaces at wire rate; the remaining 10 slots support one Gigabit Ethernet interface at wire rate. On the ERX310 router, only two Gigabit Ethernet interfaces per slot are at wire rate; therefore, only four Gigabit Ethernet interfaces are at wire rate for the entire router.
  5. For more information about bandwidth and line-rate considerations for the GE-HDE line module and the GE-8 I/O module on E Series routers, see JunosE Physical Layer Configuration Guide, Chapter 5, Configuring Ethernet Interfaces.

  6. The OC3/STM-1 GE/FE line module and OC3-2 GE APS I/O module combination does not support line rate for Gigabit Ethernet interfaces.

Link Layer Maximums

Table 3 lists link layer maximums for the ERX routers. The following notes are referred to in Table 3:

  1. The ERX1440 router supports a maximum of 48,000 interface columns of all types combined. You can use either all dynamic interfaces or a combination of dynamic and static interfaces to achieve this maximum. For bridged Ethernet, IP network, and PPP interfaces, the ERX1440 router supports a maximum of 32,000 static major interfaces. Although the ERX1440 router supports a maximum of 48,000 static major interfaces for PPPoE, the PPPoE static limit is enforced at the subinterface level, which has a limit of 32,000.
  2. The ERX705, ERX710, and ERX1410 routers support a maximum of 32,000 interfaces of all types combined; the ERX310 router supports a maximum of 16,000 interfaces of all types combined. For these routers, the interfaces can be any combination of dynamic or static.

    The JunosE Software supports up to 10,000 PPP interfaces with EAP authentication negotiation configured. Performance and scalability is unchanged when EAP is not configured.

  3. The total maximum number of Ethernet subinterfaces that can be active at any one time on an ERX310 router, an ERX7xx router, or an ERX14xx router is limited by the number of slots per chassis. Of this total, you can configure all single-tagged VLAN subinterfaces, all double-tagged S-VLAN subinterfaces, or a combination of both VLAN subinterfaces and S-VLAN subinterfaces to achieve this maximum.

    MLFR bundles per line module
    Bundles per line module are limited only by the availability of interface columns on the module. Because a bundle requires at least one interface column, the number of bundles cannot exceed the number of interface columns.

Routing Protocol Maximums

Table 4 lists routing protocol maximums for the ERX routers. The following notes are referred to in Table 4:

  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. The ERX1440 router supports a maximum of 48,000 interfaces of all types combined. You can use either all dynamic interfaces or a combination of dynamic and static interfaces to achieve this maximum. The ERX1440 router supports a maximum of 32,000 static PPP/PPPoE interfaces and a maximum of 36,500 static IP network interfaces. Bridged Ethernet does not enforce a limit so IP interfaces created on Bridged Ethernet can scale to the IP maximum of 36,500.
  3. The ERX705, ERX710, and ERX1410 routers support a maximum of 32,000 IP network interfaces; the ERX310 router supports a maximum of 16,000 IP network interfaces. For all these models, the interfaces can be any combination of dynamic or static.

  4. These values are subject to limitations on available SRP module memory, which varies according to your router configuration.
  5. 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.
  6. 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.
  7. This maximum is not valid for Frame Relay. The Frame Relay maximum is 1000 circuits over MPLS per line module, because only 1000 Frame Relay DLCIs are permitted per line module.
  8. On the ERX1440 router, you can achieve 32,767 total Martini circuits over ATM or Ethernet interfaces. For all routers, the total Martini can be any combination of external inter-router circuits and internal circuits (local cross-connects).
  9. There is no per-VR limit; all multicast routes can be on a single VR or present across multiple VRs.
  10. 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.
  11. Dynamic values represent typical limits that vary depending on configuration details and actual dynamic behavior. For dynamic values only, multiple server modules in a chassis can improve the values as long as the multiple server modules are online and the number of virtual routers configured with NAT is greater than or equal to the number of server modules. If a server module fails, the load is redistributed to the remaining server modules, with a consequent reduction in aggregate capacity.
  12. Static and dynamic translations occupy the same table; therefore, the number of static translation entries present in the table reduces the room for dynamic entries.

Policy and QoS Maximums

Table 5 lists policy and QoS maximums for the ERX routers. The following notes are referred to in Table 5:

  1. The OC48 line module supports only 131,071 entries. The GE-2 and GE-HDE line modules support only 65,535 entries.
  2. For line modules other than the GE-2, GE-HDE, and OC48/STM16 line modules, the router supports two sizes of policies: 8127 policies, each with a maximum of 32 classifiers, and 16,255 policies, each with a maximum of 16 classifiers. A combination of the two sizes of policies is also supported, in which case the total number of policies is between 8127 and 16,255, depending on the actual configuration.
  3. The GE-2, GE-HDE, and OC48/STM16 line modules support CAM classifiers instead of hardware policy assignments. For most configurations, each classifier entry in a policy consumes one CAM entry. However, a policy that has only the default classifier consumes no CAM resources. Policies that use CAM hardware classifiers consume one interface attachment resource, regardless of the number of classifier entries in a policy.
  4. For each rule that is sent from the SRC server using COPS messages to the SRC client, which is a router running JunosE Software, an entry is created in the policy table of the SRC client. A portion of the memory on the SRC client is needed to hold these policy rule entries that are transmitted to the SRC client for enforcing the policy decisions that are sent from the SRC server. The maximum number of memory blocks that is allocated to the SRC client functioning on the router for the policy rules that are sent from the SRC server is 1,024,000.
  5. You can configure compound shared shapers only on a line module with the EFA2 hardware. You can determine the support for compound shared shapers on the line module by executing the show qos shared-shaper command.

Tunneling Maximums

Table 6 lists tunneling maximums for the ERX routers. The following notes are referred to in Table 6:

  1. The SM supports any combination of DVMRP, GRE, and L2TP tunnels up to a maximum of 8000 tunnels; however, no more than 4000 tunnels can be DVMRP or GRE tunnels in any combination. The ISM supports any combination of DVMRP, GRE, and L2TP tunnels over IPsec, up to a maximum of 5000 tunnels; however, no more than 4000 tunnels can be DVMRP or GRE tunnels.
  2. You can have no more than 8000 L2TP/IPsec sessions per chassis.
  3. For more information about supported L2TP sessions and tunnels, see JunosE Broadband Access Configuration Guide, Chapter 12, L2TP Overview.

Subscriber Management Maximums

Table 7 lists subscriber management maximums for the ERX routers. The following notes are referred to in Table 7:

  1. DHCP relay proxy maintains a list of active DHCP clients up to a maximum of 100,000 clients per chassis for all virtual routers. DHCP relay does not maintain a list of DHCP clients.
  2. DHCP relay proxy is notified of DHCP client deletions and subsequently deletes the client's host routes. In contrast, DHCP relay is not notified of DHCP client deletions, so the host routes for deleted clients remain in DHCP relay until you permanently delete them with the set dhcp relay discard-access-routes command. A maximum of 100,000 host routes for DHCP clients can be stored for all DHCP relay and DHCP relay proxy instances (that is, for all virtual routers).

  3. The ERX1440 router supports a maximum of 48,000 interface columns of all types combined. You can use either all dynamic interfaces or a combination of dynamic and static interfaces to achieve this maximum. For bridged Ethernet, IP network, and PPP interfaces, the ERX1440 router supports a maximum of 32,000 static major interfaces. Although the ERX1440 router supports a maximum of 48,000 static major interfaces for PPPoE, the PPPoE static limit is enforced at the subinterface level, which has a limit of 32,000.
  4. The ERX705, ERX710, and ERX1410 routers support a maximum of 32,000 interfaces of all types combined; the ERX310 router supports a maximum of 16,000 interfaces of all types combined. For these routers, the interfaces can be any combination of dynamic or static.

    The JunosE Software supports up to 10,000 PPP interfaces with EAP authentication negotiation configured. Performance and scalability is unchanged when EAP is not configured.

  5. For DHCPv6 local server, up to 32,000 subscribers and clients are supported on PPP/ATM and PPPoE/ATM with dynamic interfaces. Interface flapping tests have been qualified for 8000 subscribers and interfaces.

    Informational Note: The system maximum and line card maximum values mentioned in the tables are for single dimension scaling only. We recommend that you test scenarios that require scaling of multiple features to the maximum values concurrently, before deploying.
    For example, on ERX1440 routers, we support 48,000 PPP subscribers and 1, 500, 000 BGP 4 routes (NLRI). These values are independent of each other. We recommend that you test that the system can concurrently support 48,000 PPP subscribers and 1,500,000 BGP 4 routes (NLRI), before deploying.
