Juniper Routing Labs

Learn how Juniper aggregate routes summarize multiple networks into a single routing table entry, with a route preference of 130, reject or discard behavior, and at least one contributing route.

Explore Junos generate route concepts and how summary routes reduce routing table size. Learn differences between generate route and aggregate routes, including next hop, contributing route, and route preference.

Explore how to create and configure static routes within multiple Juniper logical systems, enabling tunnel services and assigning interfaces, then verify reachability with cross-system pings.

Discover how to partition a physical router into logical systems, create routing instances as virtual routers, assign interfaces, configure IPv4 addresses, and test connectivity with ping.

Configure GRE on Juniper routers by creating tunnel interfaces, assigning physical and loopback IP addresses, and setting tunnel source and destination. Enable OSPF and verify connectivity with ping.

Configure OSPF using routing instances to create virtual routing tables and isolate customer traffic, then assign interfaces and verify with show commands.

Configure OSPF internal summarization on the ABR between area zero and area one, using area range to summarize 192.168.0.0/16 and verify the summarized routes in the OSPF database.

Configure bgp across logical systems on Juniper routers by partitioning a physical router into ls1 and ls2, fifteen logical systems, and assigning interfaces, ip addresses, and neighbor relationships.

Configure BGP neighbors and AS path prepend to outbound routes, influencing inbound paths, and use policies to advertise networks while prepending the AS number to steer toward the shortest path.

Learn to configure BGP confederation on Juniper devices to prevent loops and avoid full-mesh neighbors by dividing the AS into sub ASes, defining the parent and members.

Secure the BGP session with IPsec by creating a bidirectional security association in transport mode using ESP for encryption and authentication between neighbors.

Configure Juniper ebgp multihop to establish an external bgp neighbor session between two routers using loopback addresses, set ttl, and add a static route to reach the remote network.

Configure is-is routing to enable intra area routing with L1 and L2 adjacencies, using different area IDs and unique system IDs.

configure ipv6 router advertisement on juniper to enable slaac and auto configure host ipv6 addresses from the router prefix, using the 48-bit mac to form the interface id.

Configure ipv6 router advertisements in juniper to enable hosts to auto-configure addresses using a /64 prefix and a 48-bit mac-based interface id (eui-64).

Configure IPv6 addresses on Juniper interfaces with a /64, where the interface ID is auto-derived, then create a static route with the next hop and verify connectivity with ping.

Configure IPv6 redistribution between RIPng and OSPFv3 across three routers, with Vm2 as the border router implementing two policies to redistribute from RIP to OSPFv3 and back.

Configure PIM dense mode on Juniper and Cisco to enable multicast forwarding using s,g notation. Learn to verify neighbors and routes with show commands and a test ping to 239.1.1.1.

Configure bgp confederation between Juniper and Cisco to prevent loops and avoid full mesh by dividing the as into subareas 11 and 12 and establishing neighbor relationships.

Configure an IPv6 static route between Juniper and Cisco devices, assigning IPv6 addresses to connected interfaces and enabling IPv6 unicast routing. Verify connectivity with ping and by inspecting IPv6 routes.

This lecture demonstrates configuring MPLS between Cisco and Juniper, using LDP and OSPF, with VRF routing, route distinguishers and VPNv4 BGP to exchange labeled and unlabeled packets.

Learn how MPLS uses label push, swap, and pop across core routers, and configure LDP, OSPF, VRFs with route distinguishers and targets to enable MPLS VPNs and AS-override.
