Basic Multicast Test Cases

Test 1-

Verify multicast forwarding with extended input access lists for unicast traffic.

1. configure multicast
2. create Multicast stream
3. create unicast stream
4. Configure Extended (input) ACL on RP ingress interface (normal or H/w acl) for unicast traffic
5. send multicast traffic
6. send unicast traffic
7. Multicast traffic through, with ACL permit, unicast packets through and with drop option, unicast packets are dropped.

I’m using normal ACL here. Please confirm.

Test 2-

Verify multicast forwarding with extended output access lists for unicast traffic

1. configure multicast
2. create Multicast stream
3. create unicast stream
4. Configure Extended (output) ACL on RP egress interface for unicast traffic
5. send multicast traffic
6. send unicast traffic
7. Multicast traffic through, with ACL permit unicast packets through and with drop option, unicast packets are dropped.

Test 3-

Verify Multicast filtering using 1 line E-ACL on a single port matching multicast destination.

1. configure multicast
2. create Multicast stream
3. Configure Extended (input) ACL on RP ingress interface for multicast traffic (mcast group address)
4. send multicast traffic
5. Multicast traffic through, with ACL permit, packets through and with drop option, packets are dropped.

Test 4-

Verify Multicast filtering using a multiple line E-ACL on multiple slots, matching multicast destination with fabric duplication. (Multiple slots in which similar line cards reside, multiple slots in which different flavors of line card reside)

1. Configure multicast.
2. create Multicast stream
3. Configure Extended (input) ACL on RP on slots (passing all interfaces in the suite line??)
4. send multicast traffic
5. Multicast traffic through, with ACL permit, packets through and with drop option, packets are dropped.

Test 5-

Verify Multicast filtering using Multiple line E-ACL‘s on multiple ports matching multicast destination with Tx duplication.(Multiple ports of a line card)

1. configure multicast
2. create Multicast stream
3. Configure Extended (input) ACL on RP one slot???
4. send multicast traffic
5. Multicast traffic through, with ACL permit packets are through and with drop option, packets are dropped.

Please correct the steps (3) if not.

Test 6-

Verify multicast forwarding with iCAR

1. configure multicast
2. create Multicast stream
3. Configure input CAR on ingress of RP with access-group multicast

R4(config-if)#rate-limit input access-group 101 8000 ?

WORD 1,000-2,560,000,000 bytes for normal burst size (postfix k, m, g

optional; comma allowed if used properly)

R4(config-if)#$ 1000 2000 conform-action transmit exceed-action drop

4. send multicast traffic
5. Multicast traffic will be rate-limited.

R4#sh access-lists rate-limit 101 ?

| Output modifiers

Test 7-

Verify multicast forwarding with oCAR

1. configure multicast
2. create Multicast stream
3. Configure output CAR on RP egress interface with multicast access-group
4. send multicast traffic
5. Multicast traffic through will be rate limited

Test 8-

Per slot RPF check

Verify that Multicast forwarding follows the per slot RPF rule when there are multiple equal cost path available towards the source.

1. configure multicast
2. create Multicast stream
3. For RPF check if there are more then one route towards the source the one with higher IP address would always be taken, taking more than 1 interface and creating the static routes. (Enable RPF check for the source to see if the source is reached via the interface from which packets are received.)
4. send multicast traffic
5. the packets are sent through the RPF interface (any specific commands)

Test 9-

Per port RPF check

Verify that Multicast forwarding follows the per port RPF rule when there are multiple equal cost path available towards the source.

Please add the steps.

Test 10-

Multicast load balancing using Multicast Multipath

Verify that multicast traffic can be load balanced using multicast multipath

Please add the steps.

Test 11-

RPF check when switching to a redundant forwarding path

Verify that multicast flow can be successfully switch to a redundant path when the primary path goes down.

1. configure multicast
2. creating static routes between source and RP (2)
3. create Multicast stream
4. Send multicast traffic. Traffic is through from first interface
5. Interface goes down.
6. sending traffic through the second interface
7. Multicast traffic through

Test 12-

RPF interface manipulation using static mroutes

Verify that static mroutes ca override RPF interfaces chosen by IGP/MBGP.

1. configure multicast
2. create Multicast stream
3. send multicast traffic
4. Multicast traffic through
5. creating static mroute
6. sending traffic
7. traffic is passing through new route

Test 13-

Load balancing via RPF manipulation using static mroutes

Verify that multicast traffic can be load balanced on a per source basis using static mroutes manipulation

Please add the steps.

Test 14-

Multicast forwarding in the presence of unicast traffic

Verify the coexistence of multicast and unicast traffic in line card- forwarding path

1. configure multicast
2. create Multicast stream
3. create unicast stream
4. send unicast and multicast traffic
5. send traffic

Test 15-

Disabling mroute-cache while forwarding the traffic

Test the effect of enabling and disabling multicast route caching while traffic is flowing

1. configure multicast
2. create Multicast stream
3. send multicast traffic
4. Multicast traffic through,
5. disabling mroute-cache
6. check mroute-cache
7. enable mroute-cache
8. check mroute-cache

Test 16-
