| # RT-2.17: IS-IS Graceful Restart Restarting | ||
|
|
||
| ## Summary | ||
|
|
||
| - test verify isis garceful restarts support restarter mode. | ||
|
|
||
| ## Testbed type | ||
|
|
||
| * https://github.com/openconfig/featureprofiles/blob/main/topologies/atedut_2.testbed | ||
|
|
||
| ## Procedure | ||
|
|
||
| #### Initial Setup: | ||
|
|
||
| * Connect: | ||
| * DUT port-1 to ATE port-1 | ||
| * DUT port-2 to ATE port-2 | ||
|
|
||
| * Configure IPv4 and IPv6 addresses on DUT and ATE ports as shown below | ||
| * DUT port-1 IPv4 address ```dp1-v4 = 192.168.1.1/30``` | ||
| * ATE port-1 IPv4 address ```ap1-v4 = 192.168.1.2/30``` | ||
|
|
||
| * DUT port-2 IPv4 address ```dp2-v4 = 192.168.1.5/30``` | ||
| * ATE port-2 IPv4 address ```ap2-v4 = 192.168.1.6/30``` | ||
|
|
||
| * DUT port-1 IPv6 address ```dp1-v6 = 2001:DB8::1/126``` | ||
| * ATE port-1 IPv6 address ```ap1-v6 = 2001:DB8::2/126``` | ||
|
|
||
| * DUT port-2 IPv6 address ```dp2-v6 = 2001:DB8::5/126``` | ||
| * ATE port-2 IPv6 address ```ap2-v6 = 2001:DB8::6/126``` | ||
|
|
||
| * Create an "target IPv4" network i.e. ```ipv4-network = 192.168.10.0/24``` attached to ATE port-2 and inject it to ISIS. | ||
|
|
||
| * Create an "target IPv6" network i.e. ```ipv6-network = 2024:db8:128:128::/64``` attached to ATE port-2 and inject it to ISIS. | ||
|
|
||
| * Configure ISIS | ||
| * Configure separate ISIS emulated routers, one on each ATE ports-1, port-2 | ||
| * Enable IPv4 and IPv6 IS-IS L2 adjacency between ATE port-1 and DUT port-1, DUT port-2 and ATE port-2 in point-to-point mode. | ||

| ### RT-2.17.1 CONTROLLER-CARD switchover [TODO: ] | ||
| #### | ||
|
|
||
| * Generate traffic form ATE port-1 to "target IPv4" and "target IPv6" networks (ATE port-2) | ||
| * Verify traffic is recived on ATE port-2 | ||
| * Using gNOI SwitchControlProcessor call initiate CONROLER-CARD switchover. | ||
| * Verify traffic is recived on ATE port-2 during restart time ( no losses ) | ||
| * Wait 60 sec. | ||
|
|
||
| ### RT-2.17.2 DUT ISIS restart [TODO: ] | ||
| * Generate traffic form ATE port-1 to "target IPv4" and "target IPv6" networks (ATE port-2) | ||
| * Verify traffic is recived on ATE port-2 | ||
| * Using gNOI KillProcess w/ SIGNAL_KILL call restart process serving ISIS (implementation dependednt). This try to simulate ISIS crash due to unexpected error. | ||
| * Verify traffic is recived on ATE port-2 during restart time ( no losses ) | ||
| * Wait 60 sec. | ||
