### JunosE 12.0.0 Release Notes

> ### E120 and E320 System Maximums

> The following tables provide system maximums for the E120 router and the E320 router.

> #### General System Maximums

> Table 8 lists some general system maximums for the E120 router and the E320 router. The following notes are referred to in Table 8:

> 1. The maximum number applies to any combination of VRs and VRFs. The number of VRs and VRFs that you can configure depends on your configuration. You cannot achieve the maximum number if each VR and VRF instance is running a routing protocol.
> 2. The maximum of 3000 VRs and VRFs can be achieved only with the SRP-120 and SRP-320 modules, which have 4 GB of memory. The limits cannot be achieved with the SRP-100 module, which has 2 GB of memory.

> #### Physical and Logical Density Maximums

> Table 9 lists physical and logical density maximums for the E120 router and the E320 router. The following notes are referred to in Table 9:

> 1. Wire rate indicates the port density that supports maximum (wire-rate) performance. Oversubscribed indicates the port density possible if you are willing to accept less than wire-rate performance by oversubscribing the available fabric
> 2. With a 120 Gbps configuration on the E120 router, you can install up to 6 combinations of ES2 10G Uplink LMs, ES2 10G LMs, or ES2 10G ADV LMs in slots numbered 0-5. You can install a maximum of 6 active ports and 6 redundant ports at any time.

> With a 100 Gbps fabric configuration on the E320 router, you must install the ES2 10G Uplink LM or the ES2 10G LM in either of the E320 router turbo slots (2 and 4). When the ES2 10G Uplink LM or the ES2 10G LM is installed in slot 2 or slot 4, you cannot install another line module in slot 3 or slot 5. In this case, you can only install the ES2 4G LM in slots 0–1 and 6–11; therefore, the maximum number of ports and the forwarding performance per chassis is reduced for the IOAs that pair with the ES2 4G LM.

> With a 320 Gbps fabric configuration on the E320 router, you can install up to 12 combinations of ES2 10G Uplink LMs, ES2 10G LMs, or ES2 10G ADV LMs in slots numbered 0-5 and 11-16. You can install a maximum of 12 active ports and 12 redundant ports at any time.

> #### Link Layer Maximums

> Table 10 lists link layer maximums for the E120 router and the E320 router. The following notes are referred to in Table 10:

> 1. On the ES2 10G LM, ES2 10G ADV LM, or ES2 10 G Uplink LM, you can have configurations with up to 100,000 static entries that support 100,000 DHCP relay proxy clients. You can have an additional 28,000 static or dynamic entries for network resources, such as RADIUS and DHCP servers. However, the total number of dynamic entries in the ARP table is still restricted to a maximum of 32,768 per line module.
> 2. On the E120 router, the SRP-120 and the SRP-320 support a maximum of 64,000 interfaces.

> #### 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.

> #### Policy and QoS Maximums

> Table 12 lists policy and QoS maximums for the E120 router and the E320 router. The following notes are referred to in Table 12:

> 1. For more information about system resource requirements for nodes, queues, and shadow nodes, see JunosE Quality of Service Configuration Guide, Chapter 15, QoS Profile Overview. QoS is supported on all E Series line modules except for the ES2 10G Uplink LM.
> 2. For all line modules the maximum number of IPv4 or IPv6 or VLAN policy attachments is determined by the maximum number of interfaces multiplied by the number of attachment resources that are currently used. Attachment resources are only used when you attach the policy.

> The line modules support policy attachments based on the following considerations:

> - IPv4—Up to 2 ingress policy attachments and 1 egress policy attachment
> - IPv6—Up to 2 ingress policy attachments and 1 egress policy attachment
> - IPv4 secure policy—The ES2 4G LM, the ES2 10G LM, and the ES2 10G ADV LM support up to 1 ingress policy attachment and 1 egress policy attachment
> - IPv6 secure policy—The ES2 4G LM supports up to 1 ingress policy attachment and 1 egress policy attachment
> - VLANs—Up to 1 ingress policy attachment and 1 egress policy attachment
> 3. Secure policies are not supported on the ES2 10G Uplink LM. IPv6 secure policies are not supported on the ES2 10G LM.

> #### Tunneling Maximums

> Table 13 lists tunneling maximums for the E120 router and the E320 router. The following notes are referred to in Table 13:

> 1. The ES2-S1 Service IOA 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.
> 2. For more information about supported L2TP sessions and tunnels, see JunosE Broadband Access Configuration Guide, Chapter 11, L2TP Overview.

> #### Subscriber Management Maximums

> Table 14 lists subscriber management maximums for the E120 router and the E320 router. The following notes are referred to in Table 14:

> 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.

> 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).

> 2. On the E120 router, the SRP-120 and the SRP-320 support a maximum of 64,000 interfaces.

> On the E320 router, the SRP-320 supports a maximum of 96,000 interfaces. The SRP-100 supports a maximum of 64,000 interfaces.

> 3. 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.
