What's Changed

• Peer PE device peer-id value can only be 1 or 2.

• You are required to configure the loopback subnet addresses for each peer PE device using the new loopback-subnet peer1-subnet and loopback peer2-subnet options at the edit services evpn device-attribute hierarchy level. The commit script uses these values for each peer PE device's loopback subnet instead of deriving those values on each PE device. The loopback-subnet option at the edit services evpn device-attribute hierarchy level has been deprecated.

• If you configure the no-policy-and-routing-options-config option, you must configure a policy statement called EXPORT-LO0 that the default underlay configuration requires, or configure the new no-underlay-config option and include your own underlay configuration.

• The commit script generates "notice" messages instead of "error" messages for configuration errors so you can better handle edit services evpn configuration issues.

• The commit script includes the element names you configure (such as IRB instance names and server names) in description statements in the generated configuration.

This feature also now includes a few new options so you have more flexibility to customize the generated configuration:

• no-underlay-config at the edit services evpn hierarchy level—To provide your own underlay peering configuration.

• mtu overlay-mtu and mtu underlay-mtu options at the edit services evpn global-parameters hierarchy level—To change the default assigned MTU size for underlay or overlay packets.

Change in options and generated configuration for the EZ-LAG configuration IRB subnet-address statement—With the EZ-LAG subnet-address inet or subnet-address inet6 options at the edit services evpn evpn-vxlan irb irb-instance hierarchy, you can now specify multiple IRB subnet addresses in a single statement using the list syntax addr1 addr2 ?. Also, in the generated configuration for IRB interfaces, the commit script now includes default router-advertisement statements at the edit protocols hierarchy level for that IRB interface.

[See subnet-address (Easy EVPN LAG Configuration).]

Ability to commit extension-service file configuration when application file is unavailable—When you set the optional option at the edit system extension extension-service application file file-name hierarchy level, the operating system can commit the configuration even if the file is not available at the /var/db/scripts/jet file path.

See file (JET).

XML output tags changed for request-commit-server-pause and request-commit-server-start (ACX Series, EX Series, MX Series, QFX Series, SRX Series, and vSRX)—We've changed the XML output for the request system commit server pause command (request-commit-server-pause RPC) and the request system commit server start command (request-commit-server-start RPC). The root element is <commit-server-operation> instead of <commit-server-information>, and the <output> tag is renamed to <message>.

NETCONF <copy-config> operations support a file:// URI for copy to file operations (ACX Series, EX Series, MX Series, QFX Series, SRX Series, and vSRX)—The NETCONF <copy-config> operation supports using a file:// URI when <url> is the target and specifies the absolute path of a local file.

[See <copy-config>.]

ephemeral-db-support statement required to configure MSTP, RSTP, and VSTP in the ephemeral configuration database (ACX Series, EX Series, and QFX Series)—To configure Multiple Spanning Tree Protocol (MSTP), Rapid Spanning Tree Protocol (RSTP), or VLAN Spanning Tree Protocol (VSTP) in the ephemeral configuration database, you must first configure the ephemeral-db-support statement at the [edit protocols layer2-control] hierarchy level in the static configuration database.
