Which address range is used for source-specific multicast?
Which address range is used for source-specific multicast?
The address range used for source-specific multicast is 232.0.0.0/8. This range is specifically designated for SSM by the Internet Assigned Numbers Authority (IANA). SSM allows for more efficient routing of multicast streams from a specific source to multiple receivers.
Which three configuration parameters must match on all switches within the same MSTP region? (Choose three.)
In Multiple Spanning Tree Protocol (MSTP), for switches to be in the same MSTP region, three specific configuration parameters must match: the VLAN to instance mapping, the revision level, and the configuration name. The VLAN to instance mapping determines which VLANs are part of which MST instances. The revision level is a user-defined value that identifies the region version, and the configuration name is the alphanumeric identifier for the region. These parameters ensure that all switches in the same MSTP region share a consistent topology view for optimal spanning tree calculations.
Which two statements are correct about the deployment of EVPN-VXLAN on QFX Series devices? (Choose two.)
Junos OS supports ingress replication for BUM traffic forwarding, which means that to flood traffic to remote PE routers, the traffic must be replicated once for each remote PE router. Additionally, in an EVPN-VXLAN environment, Type 1 route advertisements always have the single-active flag set to 0. This indicates that all links associated with the Ethernet segment can be used for forwarding data, thus enabling active-active forwarding. Juniper QFX devices only support this active-active forwarding mode.
Your enterprise network is running BGP VPNs to support multitenancy. Some of the devices with which you peer BGP do not support the VPN NLRI. You must ensure that you do not send BGP VPN routes to the remote peer.
Which two configuration steps will satisfy this requirement? (Choose two.)
To ensure BGP VPN routes are not sent to a remote peer that does not support VPN NLRI, you should configure an export policy on the local BGP peer and use the apply-vpn-export feature. The export policy on the local BGP peer will prevent VPN routes from being sent to the remote peer. The apply-vpn-export feature applies export policies specific to VPN routes, ensuring that these routes are not advertised to peers that cannot handle them.
You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
In this scenario, which area is needed to accomplish this task?
To create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs, you need a totally stubby area. A totally stubby area limits the types of LSAs allowed within it to only intra-area routes and a default route, effectively excluding Type 3, 4, and 5 LSAs, thus achieving the requirement stated in the question.
