10.2 Default Destination Address Selection (Selezione Predefinita dell'Indirizzo di Destinazione)

Le regole di selezione dell'indirizzo di destinazione, in combinazione con la policy table predefinita e le regole di selezione dell'indirizzo sorgente, producono il seguente comportamento:

Esempio 1:

  • Candidate Source Addresses: 2001:db8:1::2 or fe80::1 or 169.254.13.78
  • Destination Address List: 2001:db8:1::1 or 198.51.100.121
  • Result: 2001:db8:1::1 (src 2001:db8:1::2) then 198.51.100.121 (src 169.254.13.78) (prefer matching scope)

Esempio 2:

  • Candidate Source Addresses: fe80::1 or 198.51.100.117
  • Destination Address List: 2001:db8:1::1 or 198.51.100.121
  • Result: 198.51.100.121 (src 198.51.100.117) then 2001:db8:1::1 (src fe80::1) (prefer matching scope)

Esempio 3:

  • Candidate Source Addresses: 2001:db8:1::2 or fe80::1 or 10.1.2.4
  • Destination Address List: 2001:db8:1::1 or 10.1.2.3
  • Result: 2001:db8:1::1 (src 2001:db8:1::2) then 10.1.2.3 (src 10.1.2.4) (prefer higher precedence)

Esempio 4:

  • Candidate Source Addresses: 2001:db8:1::2 or fe80::2
  • Destination Address List: 2001:db8:1::1 or fe80::1
  • Result: fe80::1 (src fe80::2) then 2001:db8:1::1 (src 2001:db8:1::2) (prefer smaller scope)

Esempio 5:

  • Candidate Source Addresses: 2001:db8:1::2 (care-of address) or 2001:db8:3::1 (home address) or fe80::2 (care-of address)
  • Destination Address List: 2001:db8:1::1 or fe80::1
  • Result: 2001:db8:1::1 (src 2001:db8:3::1) then fe80::1 (src fe80::2) (prefer home address)

Esempio 6:

  • Candidate Source Addresses: 2001:db8:1::2 or fe80::2 (deprecated)
  • Destination Address List: 2001:db8:1::1 or fe80::1
  • Result: 2001:db8:1::1 (src 2001:db8:1::2) then fe80::1 (src fe80::2) (avoid deprecated addresses)

Esempio 7:

  • Candidate Source Addresses: 2001:db8:1::2 or 2001:db8:3f44::2 or fe80::2
  • Destination Address List: 2001:db8:1::1 or 2001:db8:3ffe::1
  • Result: 2001:db8:1::1 (src 2001:db8:1::2) then 2001:db8:3ffe::1 (src 2001:db8:3f44::2) (longest matching prefix)

Esempio 8:

  • Candidate Source Addresses: 2002:c633:6401::2 or fe80::2
  • Destination Address List: 2002:c633:6401::1 or 2001:db8:1::1
  • Result: 2002:c633:6401::1 (src 2002:c633:6401::2) then 2001:db8:1::1 (src 2002:c633:6401::2) (prefer matching label)

Esempio 9:

  • Candidate Source Addresses: 2002:c633:6401::2 or 2001:db8:1::2 or fe80::2
  • Destination Address List: 2002:c633:6401::1 or 2001:db8:1::1
  • Result: 2001:db8:1::1 (src 2001:db8:1::2) then 2002:c633:6401::1 (src 2002:c633:6401::2) (prefer higher precedence)
