You can set up captive portal authentication on your switch to redirect all Web browser requests to a login page that requires users to input a username and password before they are allowed access. Upon successful authentication, users are allowed access to the network and redirected to the original page requested. Junos OS provides a customizable template for the captive portal window that allows you to easily design and modify the look of the captive portal login page. You can modify the design elements of the template to change the look of your captive portal login page and to add instructions or information to the page. You can also modify any of the design elements of a captive portal login page. The first screen displayed before the captive login page requires the user to read the terms and conditions of use. By clicking the Agree button, the user can access the captive portal login page.https://www.juniper.net/documentation/us/en/software/junos/user-access/topics/topic-map/user-authentication-captive-portal.html

BUM Traffic Forwarding

Junos devices that use MPLS encapsulation for EVPNs can only use ingress replication at this time.

Ingress replication means, to flood traffic to remote PE routers, the traffic has to be replicated, once for each remote PE router.

The EVPN label for this BUM traffic is learned per PE router from the route type 3, inclusive multicast Ethernet tag route.

This table shows the format of the inclusive multicast Ethernet tag route.

All-Active Redundancy (4)

This diagram shows the format of the type 1 route, A-D route per ES. The split horizon label is advertised as part of an extended community attached to the type 1 route. The split horizon label is also called the ESI label. The extended community also indicates what type of redundancy mode is used for this given ESI: single-active represented by binary 1 or active-active represented by binary 0.
